I had just about decided to upgrade my current setup Core 2 Duo E4500 Asus P5-KPL-VM ATI3650 setup and just replace the 3650 with a 4550 or 4650. The main reason for this is to get HD audio (LPCM over HDMI). Then I came across an article about the Geforce 9300 GPU (this is part of NF730i chipset?) and Intel G45 chipset. Now I am very confused as to which way to go A 4550 is going to cost £50, a 4650 will be £70. A new mobo will be about £90 for either chipset. The mobo option is going to cost more but would clear up some slots (one for the graphics card and one for the sound card I currently have as my mobo does not have SP/DIF out) Main criteria is to be able to get out HD audio over HDMI but also to have enough grunt to do a decent job of de-interlacing 1080i material and to cope happily outputting 1080p from BD (including 1080p/24) Suggestions??
