you may run into fps issues due to it being a 4100 rig.
The GTX 680 4GB? If that's what you mean, I have absolutely NO plans of installing the 680 into my FX-4100 setup. (The FX-4100/Radeon 5970 2GB setup that I had didn't go too well together. That's why I was more than willing to replace the 5970 2GB with a Radeon 5870 1GB). A 4100 and 5870 pair does better in my opinion than a 4100 and 5970.
I will be replacing my GTX 550Ti 2GB with the 680 4GB whenever it gets here. I am fairly certain my i5-2500K and the GTX 680 will "play nice".
Overderadrating a little?
This show the 680 hitting in the low 20fps in games.

Its not the average FPS that matters, its the MIN. If that is below 30FPS, the game ill be terrible to play, particularly first person shooters.
No man. It depends on where and when that min FPS comes in. My FPS has never dropped below 45 in any game other than GTA4 and Arma2. I get over 80 FPS in the Forest demo from the Cryengine 3 with everything maxed and it never goes below 60.
If you average 45, and for a split second you drop to 25 and stay above 40 for the rest of the time that split second drop doesnt mean anything.
With those benchmarks, its hard to tell how that minimum FPS was experienced. Average is more important.
