Okay, I've decided to try multiboxing whenever my rig comes through the door and I'd like to know if it will run 2 accounts at the same time well, and any tips for a newbie.

AMD Phenom 9950BE 2.6Ghz - OClocking as close to 3GhZ as I can without messing around with voltage too much.

4Ghz DDR2 RAM - 800MhZ

Nvidia Gefore 9800GTX+ - 512MB DDR3

Will be running Vista 64bit, Windows 7 64bit whenever I can get a hold of it.

Thermaltake Soprano case, probably going to add better fans/heatsinks to rig if it gets a bit hot.

750W PSU

Asrock K10N78FullHD-hSLI R3.0 Mobo

Should this run 2 okay, or will I have any problems ?

Cheers
