I'm experienced in building everyday use PC's for myself as well as friends and family, but not sure quite what I'm getting into with a gaming build. I'm not dead set on anything in the above list, I could even go either way as far as AMD or Intel processors. I would like to keep it a Micro ATX build, unless of course there's a good reason I should not. Also what kind of gaming performance could I expect out of this machine? I would like to run Crysis (even if at lower settings) as well as Borderlands, COD4, MW2 to name a few. Any advice would be greatly appreciated. Thanks in advance!

If you are looking for something a bit more powerful, for about the same price range...

I know that is a great machine, because it is mine lol. I am selling it because I build/buy/sell computers and I have entirely too many on hand--I want to move out all my old ones.

Hope this was helpful, you just happened to be looking for a machine very similar to mine it appears.

Worth a look! You will find it has some higher quality components than your original choices.

You want $900 for that? I have a Q9550 with X48 chipset, Antec P182 case I'll sacrafice for $800

You should see the stuff custom PC builders get away with here in Maine--very sub-par machines for $500-750 and they label them "gaming machines" and people think they are good. I just try to sell good machines for the best price I can.

Not trying to fire up an argument--just saying, all of my components have been specifically selected to work great with each other and I don't skimp on any parts. I could have easily put DDR2 in the machine and saved a ton of money, but that isn't what I was going for. Maybe it's just me, I like using parts I like from brands I trust--and I wouldn't pass on to my clients things that I wouldn't use myself.

Good memory, the CL is good and the voltage too.

For the case, look this, is expensive, but really good.

Some great suggestions there, I actually just used that same power supply for a build I did for my cousin--very nice for the price/performance ratio.

Personally, I would suggest a Western Digital Caviar Black hard drive--again, for price/performance ratio it is nearly unbeatable IMO.

I would also recommend Corsair RAM, I have always been a loyal Corsair user--simply because it has always worked for me--ALWAYS. I have used gSkill once, and it was fine--but for high end machines, I prefer high end memory--you get what you pay for, yah?

All in all, the above has some great ideas.

I've actually had better luck with G.Skill, Crucial, and Geil than Corsair or OCZ.
I've been using Mushkin lately. Their ram wasn't that expensive before when I was buying them.
Now all their prices have jumped significantly because people have found out they make ram
with tight timings. So far so good on all my Mushkin ram. I've heard horror stories about Corsair Dominators, but
I'm was fortunate enough to not experience any of that.

The only ram I had problems with was OCZ platinum. I had 3 sets die in the past 3 months. RMA takes forever
because they don't have any in stock in their warehouse so they have to ship it from Taiwan. It took them them
almost 2 months to ship me my first set. I just got it yesterday. I'm still waiting on the other sets.

Just do a Google search for "Samsung F3 platter density" to verify that the F3 uses 500GB platters. The cache size has little affect on drive speed.

Like I said, the WD drives are nice. I actually have 5 WD drives in my computer at home and have never had one fail. I'm just saying that you can get better performance for cheaper. Neither drive is a bad choice.

Looks like you've got a great build on your hands, courtesy of people donating their time and expertise! Build that beast.
