I have P4 2.2 Ghz on a Gigabyte Motherboard running at 400Mhz FSB with a G-Force 3 Graphics card.I would like to upgrade this setup but my problem is that you can no longer get P4s that run at 400Mhz FSB. So an upgrade would mean either a new Motheboard, CPU and memory or new graphics card. Cant have both due to cost. So what would give me the best perfomance boost for gaming, a new top of the range graphics card or motherboard to a P4 with 800 Mhz fsb and get the graphics card at a later date. the easyest route would be to put in a new graphics card but would I get the full perfomance with my set up.😕
