AGP or PCI-Express? I'm not a massive gamer but I treated myself to a new game today, installed it and then found out my graphics card wasn't quite good enough to run the game. I have a GeForce 6200 and it wanted the Geforce 6600 and above, typical isn't it! I thought a while ago about upgrading my computer but have put it off until now. I currently have the Asus K8N mother board running a AMD Sempron 3000+ and the Geforce 6200 grpahics card as I mentioned above. I have been looking at parts to build a new PC and will probably end up getting the following mother board and processor: - Mother Board = Asus A8V-XE S939, PCI-E, SATA2, Lan, 5.1Snd, ATX Processor = AMD Athlon64 3700+ Socket 939 (Sandiago) CPU -Retail Box- My problem lies with the fact I know nothing at all about these new PCI-E graphics cards. I know my way around a computer inside and out, but I just havn't needed to know anything about the PCI-E therefore I don't. I know AGP is being phased out and PCI-E is to be its replacement, but thats about all I know. Can someone explain to me (in plain english) what the main differences are between AGP and PCI-Express (apart from they are different slots)? Is there any speed difference between a 256mb AGP graphics card and a 256mb PCI-Express grpahics card for example? Any recommendations?
