    A quick question:

    I was reading an article on net the other day about building you own rig and how important it was to match the CPU/FSB and the RAM etc etc (ie 800FSB with dual channel DDR400 etc).

    It also mentioned that even if you do all this wisely a wrong choice of graphics card could strangle it and you'd have wasted your money in buying carefully.

    I have selected all my other components for an upcoming build but I am not a gamer so don't need huge graphics performance so was going to save money on the card - now I'm wondering if this will be a mistake. I only want DVI output and 1600x1200 capable, don't need TV-IN, dual support etc etc.

    How do I determine from the specs of cards what is the "correct" speed match for the rest of my hardware? Or am I being misled by this article?

    All help appreciated.

    Components:
    MSI875P Neo M/B
    Intel P4 3.0 FSB800 CPU
    TwinMos PC3200 DDR400 (2 x 512 sticks)
    WD 40GB 7200 rpm
    Samsung SpinPoint 120GB 7200 rpm 8mb cache
    Asus CDRW 52X
    X-Case Metro inc 350W PSU
    2 x 80mm Cooling Fans
    Win XP Pro

    DVD writer to follow once 8X dual formats settle down.

    I was going to go with a 64mb Sapphire 7000, which is cheap, but I need help on a good choice at a keen price.

    Definitely the 7000 is the wrong card, whatever you plan to do with the PC. For HCPC you need a 9600 or better, non-Pro so fanless.

    The 9600 is important because it has the best MPEG decoder, better than the 9200 apparently. Saving a few pounds on the card is IMHO not the way to go .. IMHO 1Gb of memory is way more than you need, get 2 x 256 sticks and use the money saved on a decent graphics card. .. for an HCPC 512Mb is still too much. :)

    This rig will not be HCPC but will be doing a lot of work with DivX and XviD encoding from my DVD sources etc so specialising for HCPC is not relevant in this instance (sorry should have explained myself).
    With that in mind, what would you recommend I evaluate a card on?
    I must admit I was thinking of 2 x 256 sticks rather than the full 1024mb but ripping and encoding does (AFAIK) chomp on a fair chunk of RAM.

    Thanks for looking.

    Forgive my naive knowledge but I thought DivX and Xvid encoding was dependent on CPU power. What relevance has the video card to the quality/speed of the encode in terms of fps? I thought it was sheer computation?

    The screenshot shows the difference in hardware mpeg decodeing, sorry not really relevant how your purposes. I think you are correct, video card not relevant for DivX encoding.

    No probs - sorry if I was the source of confusion!

    With that in mind, what do you think is the minimum spec card I can get way with? I don't view DVD through my PC, my TFT is only running at 1280 x 1024. All I want is DVI out really - for example the PC I am using right now has a 64mb card in it and that's been good enough, it's just that the article I referred to earlier in thread said that a mismatched video card could significantly hinder the overall speed of the system.

    Interesting, I've never seen an example of the difference before, just assertions there are differences. :)

    I misunderstood what you were asking, thinking you were interested in video output for an HCPC or maybe image processing or something .. it's highly unusual to build a high-power system with 1Gb of memory and fast dual-channel memory and throw in a cheap and slow video card, you must have some very specialised application you want to run.

    If what you read really did say that the video card would affect the processing power of the system then that is incorrect, without seeing the comments you read I can't really comment any more except to say the video card does not affect things like, for example, video coding (since you mention DivX and XVid coding) or ripping.

    As for ripping and encoding needing a large amount of memory, my experience doesn't show that, certainly ripping is constrained by optical drive and hard disk performance, memory is barely used. For encoding I don't see why vast amounts of memory would affect throughput that mouch, again peripheral access and CPU power are the bottlenecks I'd have said.

    I am not planning to run any special apps, just wanted to spec and build a powerful PC that could do my ripping and encoding, as well as surfing, mail and Dreamweaver/Fireworks/Photoshop work all at once (or as close to it as poss). :) To that end I chose components to minimise any bottlenecking in terms of CPU power, HD access and bus speed.

    I think perhaps I should have rephrased myself more clearly (the second Red Stripe must be kicking in :D) . Given that my TFT can't run resolutions over 1280 x 1024 and I don't use the PC for DVD playback etc, can I get away with a "lower spec" Video card such as a 9200 series, seing as all it has to do is support display at 1280 x 1024 and have a DVI out port? I have seen 128mb 9200 Sapphire cards with DVI for as low as £40.

    I apologise for my confusing you all :zonked:

    Well the 7000 you originally suggested would have a hard time coping with Photoshop I think, not to mention 1280x1024, and I'm not sure that can be done in 32-bit with only 64Mb or not.

    A 9200 is certainly more up to the job all round and at that price I think is a very good buy. :smashin:

    Cheers - thanks for your time.

    Right then, look out credit card!

    PS
    100 posts! Yeah, baby!!:clap:

    Let's hope you don't need another 100 to get your new system up and running. :D

    Good luck.

    Hope I'm not hijacking the thread, but if you don't match your speeds, ie; AMD 2500+ 333FSB with PC3200 400FSB RAM, does this actually slow you down or are you just wasting the 400 bit of the RAM.

    Cheers

    It's as you suggest, you're just wasting the ability of the RAM to work at 400, it'll run at the slower of the two speeds.

    In general, there are some minor exceptions, you can always connect a component capable of running at a higher speed to a slower bus, it'll just run at the reduced speed.
