I hope i'm posting in the correct section, sorry if i'm not.

Anyway, i'm looking to build a computer and spend under $900 on the comp itself. This excludes the monitor, keyboard, mouse, ect.

The parts I've been looking at would be these

Processor
Intel I5-2500k

Graphics card
Sapphire Radeon HD 6850

Motherboard
ASUS P8P67

Power supply
Corsair HX650

Ram
Corsair vengeance 8gb

Hard drive
Seagate Barracuda 1.5tb 5900rpm Not to sure about this one. It looks as though most of the prices on HDD's are higher than they were a month or two ago.

Edit: Thanks for the warning on this I shall look for another option.

DVD drive
Asus 24x dvd burner

Case
Cooler Master Elite 430

Operating system
I was looking to install windows 7 although i'm not to keen on paying $200 for it so if anyone knows where it can be found for say $110 or less that would be appreciated.

I will probably end up buying most of the parts off amazon considering some are cheaper there and I won't be charged state sales tax or shipping as I would be on Newegg

I'm looking for any feedback on the whole system really, i'd like to build something that can run newer games on high if not the highest settings and get a playable fps, I do understand within the budget this may not be possible. Something that can be upgraded fairly easily as well if necessary. I may also be interested in overclocking once i better understand it.

Thanks in advance :3
