I've recently started playing computer games such as WoW, Skyrim, and etc. It just so happened that my motherboard decided to get fried in my normal computer yesterday and i'm now looking to build one so that I don't waste a ton of money on buying a whole one. The problem is that i've never built one before and there are too many options to choose from even after being guided from videos on websites like teksyndicate and etc. I put one together on pcpartpicker and I would like some input on whether this is good enough to play games like WoW and Skyrim on decent settings. I would also like to know whether or not I need to buy anything else at all to have a good running gaming computer. Here's the build http://pcpartpicker.com/p/rGlQ
*I would also like to see if I could put my HDD from my old computer into this new build. How can I tell if it's compatible?
No, that won't do, that psu that comes with the case will not powerup the 6870, see a good price/performance intel buid :
You have an option of latter on, switch for an i5 or i7 ivybridge with pcie 3.0 support(in the future), the psu is really a good one and for a 660 gtx will do, by the way the 660 gtx is a much powerful card than the 6870, it beats the 7850.
