Hi guys, Sorry to bother you but I need some advice. I've got an old core 2 quad clocked at 2.5ghz a core with 4GB of DDR2 800mhz ram and a msi 1GB 7850 stuck in it, as techradar recommended it. I can finally run modern games at medium settings very well and I am chuffed, chuffed until I saw this for only about £50 more: Club3D HD 7870 XT jokerCard review | Graphics cards Reviews | TechRadar From what I read, the 7870 is a good 15-20fps per game better than the 7850 and although I only game at 1080p so 1GB of video ram works fine, I want to future proof a little. I only have a 500w coolermaster psu (20amps + on both rails) - I've got an SSD,HDD and DVD drive so they much power. Would it be worth considering upgrading to the 7870 or is my machine already a chokepoint? My pci-e port is just an old x16, it's not 3.0 or anything. Thanks guys, I've been pondering this for a while!
