When I bought this computer (2010), the components were already cheap and going out of date. It does the day to day stuff well but I have seriously run into a wall with gaming even with a pretty good overclock. I can play GTA IV at full settings at about 28 fps, I drop it to low to get above 30. My favorite game though is Battlefield 3. I can only play multiplayer on low custom settings at 720p. I get about 40 frames running around but as soon as there's a good bit of action, it drops substantially.
My CPU is running 3.6GHz (360x10) The graphics card normally runs 550 mhz base, 400 mhz memory. I'm running it at 670mhz base, 580mhz memory stable.
The overclock on the graphics definitely makes a big difference. I can't wait to get my GTX 760.
The case I have doesn't have a lot of room for cable management but I managed to move enough of the mess to the empty area under my optical drive.
