I am soon going to build a computer.

My components:
Intel Core i7 2600K 3.40GHz (overclocking @ 4.60GHz) Sandybridge CPU
Asus P8P67 DELUXE Intel P67 (Socket 1155) DDR3 Motherboard
RAM: Corsair XMS3 4GB (2x2GB) DDR3 PC3-12800C9 1600MHz Dual Channel
Corsair A50 CPU Cooler
OcUK GeForce GTX 570 1280MB GDDR5 PCI-Express Graphics Card
Western Digital WD20EARS 2TB Hard Drive SATAII 64MB Cache - OEM Caviar Green
Coolermaster Silent Pro Gold 700W Modular PSU
LG BH10LS30 10x BD-RE with DVD±RW & LightScribe SATA Blu-Ray Drive
NZXT Lexa S Case

My question is what version of Windows 7 should I get with these components.

64 bit or 32 bit? (bear in mind more RAM can be added if desperately needed)

And Professional or Ultimate? (generally if both versions run just as well)


Thanks!

all version will run that setup .but ,if you want to run more than 3.5meg ram you need to run a 64 bit .version pro or ultimate would be my choice ,i have ultimate but i go it free from Microsoft for hosting a win7 release party back in sept 09,wish i had something like your upcoming setup to run it on .
check this like on differences in win7 version and then decide .
