im gonna put 4770 in crossfire. anyone know a good crossfire enabed motherboard ?

depends what processor you have, unless you want to upgrade it too

Go with the E8600, massive OC headroom and 2 cores are better than 4 cores because most software doesn't support 4 yet.

A mainstream laptop would be just fine for occasional gaming. try the new asus gaming laptops, they look good

the motherboards aren't very futureproof (new socket) but the processor should last for a few years

wait for windows 7 RC1, download and install

upgrade the CPU, GPU and the PSU and you should be fine in most if not all games

4870 1gb if you can afford it

you wouldn't get much of an advantage from it unless you got a new cpu as well as the ram...

the bottom line is you are better off getting a new computer

The 4870 is just fine for physics calculations, unless you already have the 9800gt forget it

just reformat your computer, it will get rid of it for good and any other viruses norton doesn't pick up
