Alright, so i bought a 7950 DUAL-X with boost, and it was fine for the first week or so, but now, when i play games, they're really choppy even though the FPS is locked at 60 (with v-sync on). I also have a pretty old cpu, which bottlenecks the gpu for sure (temporary, till i get an i5 4670k). Why is it choppy at 60 frames per second?
Choppy gameplay on new GPU! :/

I've only really played Call of Juraez: Gunslinger, Battlefield 3, Dead Rising: Riptide and Civilization V. Though, in Battlefield 3, it rangers from 30 to 65, so i expect a BIT of choppyness. However, CoJ and DR? These games should be playing without any jitter at all times, unless the CPU is affecting it?

I agree your CPU and/or motherboard is likely the cause but here's something to try:
Run a game at its LOWEST possible quality setting at whatever your maximum resolution is (i.e. 1920x1080). Leave VSYNC OFF for testing and FRAPS on to show your frame rate.
Now determine if you feel any lag/stuttering. If not, then raise the quality to a point the stutter is acceptable.
Choppiness at 60FPS:
Even though your GPU is updating the screen at 60FPS, it's not updating all elements. As well, that 60FPS is an average and each frame might be of different lengths; ideally at 60FPS you want ALL elements updated and ALL frames to be of exactly 1/60 seconds.
Choppiness exists when:
1) there's a CPU, GPU, memory (including hard drive) bottleneck. Some games (not most) improve with a better drive.
2) The game code is poorly written. Bethesda's game engine for Fallout 3/NV and Oblivion had lots of stutter. Stutter fixes and other workarounds exist to varying success (The Fallout NV "stutter fix" works quite well.
I can verify BF3 is very smooth on my i7-3770K and GTX680 setup.
Other:
Don't use deferred anti-aliasing in BF3. It's not a stutter issue, it just muddies the picture horribly especially in dark areas.

Could it be my RAM? I think it's defected, since it's not really a known brand nor are the two sticks from the same manufacturer. My system is a complete bottleneck, i won't worry till i upgrade the other components.

It's most likely that your CPU is the primary bottleneck. The explanation is slightly complicated.
Please try my advice on setting everything to the LOWEST settings and see if stutter exists then slowly increase the settings to see where stutter happens (try both with VSYNC ON and OFF). You SHOULD be able to have much less stutter at a lower quality setting to keep you happier until you upgrade your other components.
