whoa, where you get 16%? more like 5%. 10% at the most . . .

the 280 is even faster than the 7950 at stock.

What card do you have now, a 7950,7970, 280, or 280X?

Edited for clarity
I already have an overclocked 7950. Really pleased to see that the cheaper crossfire option is looking best!

Booker, i'll be brutal with you . . . if you are pairing the 7950s to your 6100 . . . don't.

??? That 6100 won't be bottlenecking him much, if at all, especially if it is overclocked. Definitely not in games that take advantage of all 6 threads, where that 6100 can stretch its legs. Now, would I recommend running tri-fire with it? Absolutely not. But the bottleneck he suffers with the 6100 will be at most a 10% performance hit.

I'm wishing I never 1 of my 7950s, they had problems in some games, but they were hella powerful

Wow, didn't expect to hear my 6100 might be a bottleneck! I am struggling to get decent frame rates on Arma 3 even reduced to high setting, surely not down to the cpu is it?

the 7950s are faster than this . . .

Arma i think is cpu intensive or just bork.

If memory serves me correctly, Arma 3 is CPU intensive and poorly threaded/optimized. I'm sure you can tweak the settings to reduce CPU usage (and crank up GPU intensive things like AA), but it will hold your 7950s back some.

Your CPU is pretty close to my trusty old Phenom II 965, a single 7950 is good match for a 6100. IMHO you should wait a bit and do an overhaul down the road, especially since GPU prices are so bad atm.

Probably the smart decision. In fact, I would go as far as to say get an 8350 now and wait for 7950 prices to fall and that way there will be absolutely no bottlenecks later on when you grab another GPU.

Your fx 6100 performs as a phenomII x4.so you need an inteo processor so in every game a 7950 crossfire is a bottleneck(reduced if you use 1920x1080)

And in arma III singleplayer the cpu acts like this

(Between fx 8150 and fx 4100)
