Is the i5-3570K too powerful for an HD 7770?

I intend to run a Sapphire HD7770 GHz edition OC, alongside a i5 3570K.
will this be a bottleneck? I want to run games such as skyrim or MW3 at medium/high graphics.

here's the rest of the parts:

4GB (2x2gb) Kingston 1600MHz RAM (will be adding a second set soon)
Seagate Barracuda 500GB 7200 RPM (will be adding another one to run in RAID 0)
Corsair HX 650 (will possibly be adding a second HD7770 to run in CrossFireX)
Coolermaster Hyper TX3-EVO, in push-pull configuration (will possibly be upgrading to Hyper 612)
ASRock Z77 Pro 3 Motherboard
Corsair Carbide 400r Case

cheers for any feedback

alright then, should I switch from a 3570K to an AMD FX-6100?
it would be much friendlier on my wallet.

No. No way. Invest your money in a 3570K and it will last you a good 3-4 years. You'll be itching for an upgrade for the FX-6100 a lot sooner if you decided to go down that route.

To answer your original question there's no such thing as "too powerful" but you should think about saving up and getting a more powerful single GPU than running Crossfire. A 7850/7870 will comfortably run MW3 or Skyrim at max settings.

Rest of the build looks good. Don't bother with RAID 0 with HDDs in the future though, get an SSD instead.

Spend the extra $100 and get an i5 3750K if you want real performance.. AMD processors are a joke among tech savvy builders. Sure, if you're building an email machine for your grandmother, by all means save the money and go with AMD, but for anyone into gaming, folding, video editing, etc. you will be disappointed. You get what you pay for!

If money is an issue, get an i5 2400 or 2500 (non K) or Ivy Bridge equivalent. Either is better than anything AMD has right now at stock/slight overclock speeds in regards to gaming. Techspot has done reviews on above CPU's, so do some research... you don't have far to go.

I was the big AMD fan but even I know that the new AMD cpu's suck,so I would say go with the I5 3570k,I did.
With your listed specs you can should be able too max the settings on MW3,I could with my single 7750 @ 1080
not sure on skyrim.

Skyrim's come a long way with its patches too especially on optimization. It should run good on that setup, maybe tone down AA to 4 or something but overall should be a good build

an FX-4100 wont bottleneck a 7770 from things ive read.
I would do a 6100 because you wont notice the difference unless you are using a 300 or 400 dollar graphics card.
if you wanna be more future proof I would get the i5 though, like if you were to update the graphics card in the future.

Correction; I meant i5 3570K.....sorry!

Stick with the Intel CPU. I have heard bad things about AMD Bulldozer CPUs. The CPU really can't be "too powerful" for a video card. If I were you, I would do what slh28 said and stick with the Intel, but upgrade to a better video card. As mentioned, the 7850/7870 would be great for your needs.

A Phenom II CPU (the 965BE would be my recommendation) would be a better buy compared to a Bulldozer CPU as a more budget-friendly purchase; you can probably drop the extra cash saved on a better GPU. That'd net you far more performance than a faster CPU, IMHO, and gaming performance shouldn't suffer noticeably.

With drivers 12.8 from amd, skyrim gained 50% performance on the 7770. but yeah, I would get a 7850 or a 7870 because the 7850 can oc a ton I hear. I will post some links

Just chiming in, I recently bought the 3570K and I would definitely recommend it over anything from AMD. Trying to overclock it now and I have it sitting at 4.8GHz without any drama.

My vote is to go with rage suggestion and get the faster gpu
