How bottlenecked is my set up?

I know my GPU is currently bottlenecked by my CPU, but by about how much? I have an AMD Phenom II X4 840T and a Sapphire Radeon HD 7770 1GB OC. My Mother board also only has PCIEx16 2.0 that shouldn't affect it too much, but i want to know what kind of performance increase i would get from an AMD FX-6300 in games like Skyrim. I already play on ultra with FXAA, but get around 25-35 FPS in citys. I currently run games at 1680x1050, but hope to get a 1920x1080 monitor soon.

If that's your budget then yes you should buy a second card for CF. But what i would do is sell the card you have now and then buy a good 200 dollar ish card which will be a better option.

Not at all, CPU isn't bottlenecking your GPU... you will get at most 10% in some games which is 4FPS but most of the time it'll only be under 5% performance increase which is roughly 2FPS... GPU is your only bottleneck in the games 1GB VRAM isn't enough and it's too slow

Actually, Skyrim specifically is typically CPU bound, even at high resolutions. That said, your specific upgrade path will not yield a massive increase in frame rate. You'd need to aim somewhere closer to the top of the stack for that in this specific case. Now in general, I would agree with legendkiller, that your CPU and GPU are currently fairly balanced. Maybe even a little heavy on CPU for most games. But not Skyrim.
 
Skyrim plays pretty badly on most AMD CPUs, it's just the way it is. Not sure if it's optimised for intel or w/e. You'd be looking at around 60 with some drops on a 6300. I'm surprised you can play on ultra with that GPU - monitor your CPU and GPU usage in-game, if both are maxing out then you don't have a bottleneck - if one is maxing and limiting the other then you have a bottleneck.

What's your monitor res btw?

Sorry, I meant in comparison to intel chips. :lol:
