I'm wanting to increase my gaming performance. I've got an AMD Athlon XP 2800+. I've been having blue screen issues. I'm thinking they're due to motherboard. It's either that or the processor. I've isolated all other possibilities. I'm assuming it to be a mobo problem. Now, I've got another mobo I can swap out, but it's only AGP 4x. I'm wanting to get a 6600GT instead of my current Geforce2 MX400 to hold me over until I can build a new system next year. How much of a performance hit would I take from running a 6600GT in 4x instead of 8x? I might send my other mobo back to chaintech to get it serviced, but the model i've got (7NJL6) is infamous for it's problems and I'd imagine a replacement would probably be the same. So I might end up sticking with the AGP 4x mobo, which is why I want to know if this will compromise my gaming experience?
