|yeah i've built myself two gaming rigs now and you want my advice? don't try to go top of the line.|
if your current PC is old and slow enough to make you consider upgrading, NEW, MID-RANGE hardware will blow your mind. seriously. because if you've been playing Monkey Island 2 all day, Crysis will look SICK even on lowest settings.
my point is look for like a C2D or C2Q CPU with DDR2 RAM and some kind of midrange PCIx video card (260? 280?). Just don't skimp on your PSU. You should be able to put together something real nice for $800-$1000.
oh yeah and you shouldn't need 8GB ram for gaming. i rarely (if ever) tax my 4GB.
