So I'm looking into purchasing a new GPU and would like to know if a crossfire would be worth the huge amount of savings. Nothing in my rig is Overclocked, "yet".

AMD Radeon HD 7850 1GB 256-Bit GDDR5
AMD Phenom II x4 965 BE
MSI 970A-G46 AM3+ AMD 970 + SB950 SATA 6Gb/s

Not sure if you need more on my build

Anyways, like the title says. Should I purchase a new 7850 1gb on Ebay for $80 or a brand new 770 4gb for $360-$400?
I am looking for a significant improvement in FPS.

Also would i be able to get a 2gb 7850 and crossfire that with my 1gb?
Or is there another type of card i can crossfire with my current card to make it better?

Thanks in advanced.

If you Crossfire a 2GB card and a 1GB card, it will stick to the 1GB. It wont use 2GB of VRAM. I would get the GTX 770 however, your CPU will bottleneck it. (http://www.tomshardware.co.uk/answers/id-1768769/amd-phenom-965-bottleneck-gtx-770-ghz.html). Also I think the Crossfire setup will also be bottlenecked and also have the problems that come with crossfire. I would advise getting a better CPU from the FX series e.g. the FX 8320. (Don't get the FX 4XXX series)
So get the GTX 770 less hassle than crossfire, as powerful. Then get a better cpu along the line ( e.g. FX 8320)

I would recommend going for the 770 if you an afford it. But stick to the 2GB version, no need for you to get the 4GB. The pair of 7850s in crossfire would perform better from an fps standpoint, but the problem with crossfire and sli is that when games come out they rarely work with both cards, it is often a month sometimes more before the profiles are released, and being limited to 1GB of graphics memory will hurt you as well. If you spend the $300 on a 2GB gtx 770, it will be a HUGE upgrade for you, you will be able to play new games mostly maxed at 1080p without breaking a sweat. That is what I would do anyway lol, if I had the cash. I just think using crossfire is more trouble than it is worth sometimes and I choose to avoid the headaches :) Your CPU will most likely bottleneck though like blademaster said, but you would still see a huge improvement, a CPU upgrade would be advisable at some point though.

Thanks for your input guys.
I have heard that crossfire is troublesome, but I would like to try it out sometime in hopes that the problems solved by the companies.

I guess I'll go with the 770 along with a few of my friends.

How much will my CPU bottleneck?

I figured this would happen if I upgraded but I am limiting myself to one upgrade for the next few months. I would like to see some improvements for a while and get a new CPU later.

It will bottleneck it a bit, but not a huge bottleneck, it will be more noticible with more CPU heavy games like Crysis 3 and BF4 64P
