Buying a 7870 or 7850, trying not to bottleneck.

Hey there all!

I am currently in the process of building my first gaming rig. As far as my GPU goes, I should be getting a 7870 or 7850, depending on if anything goes on sale within the next few days.


My worry is that I may end up bottlenecking with a CPU. I was looking at newegg's combo deals for cpus and mobos. While I feel like I have a general idea of what I need, I'm a little lost as to knowing what may or may not bottleneck my CPU.

Specifically I was looking at this combo deal: http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...

While this is somewhere in the mid-range of my budget, I wouldn't mind if I could spend a bit less or not, but I don't want to bottleneck my gpu so this is why I come to you guys! Thanks in advance for any answers, your help is greatly appreciated!

That cpu will be fine with a 7850 or 7870. Most games are gpu bound rather than cpu bound and pretty much any Sandy Bridge cpu will be fast enough for all but the highest end gpu (probably even then, depending on the game).

Hmm... That i3 should suffice for 7870. But, I really suggest you to get a different motherboard. The motherboard you told me about is a Mini ITX Motherboard. If you can, try getting this motherboard?

I know it is more expensive, but it's Micro ATX and easier to handle.

For the GPU, since 7870 are down to $300, you can get this:
