I have found a Samsung HDD (1TB) for about $75 dollars. Thank you Eldar. I got the suggestion for the Motherboard from a friend. I could use some help on what a good chipset is. Also, the iHAS524 from LiteOn looks good for what I need. The Thermaltakes look good, but I don't know how many watts the power supply should have. Thank you for all your help in my search for computer parts!

650w to be safe. With newer systems 700w is good and safe. Good for if your gonna upgrade later.
But a 650w should be enough.

Though I haven't gone into the new parts you shown.

Thank you Met! And Why does Eldar dislike EVGA gfx cards?

Most of the problems I did have with EVGA has been a while back. Just have seen so many of those cards go bad from my work in a computer store. The biggest things with cards though, more than the brand, is the heat sink and how hot it runs.

Also, you dont have to buy the highest card ont he market. Top card of a year or two ago is a good thing to shoot for. Just watch the reviews of anything you buy.

Eldar is right. The Most pricey one is not always the best. You may drop a few hundred bucks on one to find out in a month or two that it has failures left, and right.
Read some reviews. Find some benchmark comparisons. Don't just buy what ever cost more. Some of my best cards have been budget cards. The one I own runs every thing I throw at it, and it was under 300 bucks. Actually $230. One of my old ones. A Nvidia 280gtx BFG, was one of those cards. It cost me $420. One of the Worst over heating piles of crap I ever bought. Driver crashes, Over heat to the point the gpu would lose stability.

Never buy because of price, and hype!

I found a XFX Radeon HD 7850 for around $255, and the reviews look pretty good. They say that it's comparable to the GeForce GTX 580.

Got the laptop for 400 bucks at Costco, the RAM was 40 bucks at Fry's Electronics, and both my harddrives were gifts . The laptop will run any game from before 2008 no problem. Better than the desktop in fact. But anything new and it struggles really hard. Desktop can run most games on the highest settings. Things like Sims 3 and Skyrim it has some trouble though, so I set it to medium and it's happy again.

My laptop was bought for schoolwork. Not Gaming
