Is my CPU bottlenecking my GPU?

Hey i'm building a gaming computer and i'm on a budget. I have an amd fx 6100 CPU in my cart on Newegg, and I was just wondering if a gigabyte ultra-durable VGA series Dual fan Radeon HD 6850 is compatible with it. I'm assuming they would run fine, but i was just wondering if the 6100 will bottleneck the 6850. Also, is the fx 6100 and 6850 setup good for gaming and recording gameplay of games like skyrim and minecraft with fraps? I have 8 gb (2x4gb) ddr3 1600 mhz corsair vengeance ram btw. Thanks in advance!

I do have a hyper 212 plus im putting on it and idk if i should buy the 7750 or not because it is cheaper but only 128 bit instead of 256. I am on a budget and do not have enough money allotted to buy the 7770 :( Thanks!!!

Normal applications aren't going to hinder a 6-core cpu. You'll be fine to record your games, despite all the haters complaining about how bad the card is. I have the 4-core version and it's given me no problems. You'll be able to overclock to 4.4 GHz without changing the voltage..
I suggest getting the 6850 instead of the 7750 because of that 128-bit bus.

Ok that's what I thought because on the Play Claw website it said most recording applications take advantage of multi-core CPU's so I'm hoping Fraps will be the same because it is reliable.

just cause you cant tell that there is a problem doesnt mean theres not a problem. those cpu's bottleneck a lot of cards not just higher end cards. it also depends on the game.

Guys, the memory bus on a graphics card isn't as important as some are implying. Take a look at the GTX680's memory bandwidth....256bit memory bus (192.2GB/s, but has no problem keeping up with the GTX580's wider 384bit memory bus(192.4GB/s).

The memory bandwidth is what actually matters....

You will not have a bottleneck, I run 560's in SLI with the same processor with no problems. I have the cpu overclocked to 4.0ghz.
 
imo radeon hd 6850 is better than the radeon hd 7770. 7770 is currently quite overpriced for it's performance.
fx 6100 will be okay with a single 6850 as long as you don't do crossfirex. it might bottleneck then. if you can find a deal on 6870, even better. i don't know your gfx card budget.
make sure you have a sturdy psu to support the overclocked fx6100. it will use up quite a lot of watts when overclocked.
i agree with esrever, an ssd will be good for fraps recording and gaming. may eb a crucial m4 or something similar, if your budget allows.
memory bus width is an important factor in measuring memory bandwidth. 256 bit cards, that is why, will always be better than 128 bit cards. when memory bandwidth is similar, other factors like core clock speed, memory clockspeed, underlying architecture are also other deciding factors.
lastly, don't believe right away if someone says that they can't see any problem. doesn't mean it's not there or it's not being mitigated by other factors or no one else should not or cannot notice the problems. that's why benchmarks from tom's are a good measure of performance.

true but with that case its the cpu which was easily preventable by buying a better cpu.
