Yea 6 gig is good. Most games won't use more than 2 gigs for the game anyway (part of being 32 bit compatible) or so I'm told.

Thanks ;) also is a 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card good?

Yea looks good all you really need. Also make sure ground yourself before touching the inside of your computer. Static electricity can really fuck over your PC.

Yea as long as you keep a hand on your case most of the time it will be good try building it off carpet and on tiles or something if you really want to avoid any chance of it screwing up your PC. Buy a anti-static wristband if you are really worried about it but just keep a hold of the case and you should be fine.

Thanks for the great tips. very greatful :D

Yeah work on some tiles or something ive worked on PC's without being grounded i wouldn't advise it but if your hands are clean you could give it a shot, try and make sure all your fans are secure and that they dont rotate when your working on the PC as the fans can damage the system via electrical discharge or some shit like that xD
