Which will produce better performance?

Purchasing and using ONE Radeon HD 7950

Or

Purchasing TWO HD 7770 GHz Edition and Crossfiring?

Which would produce best results and why? Any Benchmarks for this?

Single high end is ALWAYS better, and 1 HD7950 has 3GB usable memory, 2 HD7770 will only have 1GB usable.
Xfire has numerous micro-stuttering and frame pacing issues.

Always stick with a single card if you can. Benchmarking programs might say the two 770s have greater raw power than the single 7950, but multiple gpu setups are way more hassle then they are worth. Plus, they require more power and the majority of games, from my experience, either don't utilize multi-gpu very well or at all. Stick with the 7950 or go with the Nvidia counterpart the GTX 760. I only say that because Nvidia is better overall currently imo. Hope this helps. Cheers mate!

Going for the first option will save you troubles that associates with multi gpu configuration.

I totally disagree with what people are saying about the multiple card solution . There is no question that you will get better performance from two 7770s than one 7950. First, the micro stuttering has been resolved with the latest beta driver releases. Second, it couldn't be easier to configure the cards in crossfire. You plug them both in the motherboard, you connect them with the crossfire bridge, and you click a button in catalyst control center to enable the crossfire configuration. Sure, on certain benchmarks the performance appears skewed, but in strict FPS testing which is pretty much all the human eye can see there is no questioning the performance of these two cards in crossfire.

Nvidia cards are great, but they are far more expensive and it boils down to the question of what you are really paying for. Do you want to pay more for a card that performs better in some obscure benchmark that makes no difference in practical application - okay, fine, but the question posed by OP was whether or not two 7770 in crossfire was comparable to one 7950 while being much more affordable and the question is undoubtedly yes.

Sooo you know games that use MORE than 1GB of RAM will NOT perform better on 2 HD7770s... Anyway, point is, crossfire ads PLATFORM cost and EFFORT. Larger PSU, better motherboard, driver issues. When considering EVERYTHING, single GPU will always be the better option.

PLease avoid commenting on 2 month old solved threads in the future. There are plenty unsolved threads waiting for attention. Thank you

I know it was older, but felt like commenting as it's a common question. I didn't even think PS would be an issue for most as you could run a 7770 xfire with a $50 Corsair PSU. Obviously there are clear advantages to a single card as you point out, but I think the xfire configs take a bad rap considering how inexpensive they are. I think it's tough to beat the value/performance of 2 7850 2GB cards when they are selling for about $150 each right now especially with the recently revamped drivers. This would compare favorably to a single GTX 770 and cost at least 25% less. If your on a budget and want to maximize the value then this is a good option.

If it were me personally and cost wasn't as much of an issue I would prefer 2 770s in SLI, but cost is obviously a major factor.
