Hello. This is the GPU I have
http://www.amazon.com/HIS-DisplayPort-Express-Graphics-H785QN2G2M/dp/B007HYIDTC/ref=sr_1_1?ie=UTF8&qid=1385699654&sr=8-1&keywords=his+iceq+x+7850,
and I was thinking of buying another one in the future. My specs are this:
AMD FX-8350 stock speeds @4.0ghz
MSI 970A-G46 motherboard
HIS IceQ X 256bit 2gb OC'd to 1000mhz core clock 1400mhz memory clock
SeaSonic 620W M12II PSU
antec 300
4 case fans
hyper 212 evo
WD blue 1tb
thanks for any input. is it worth it for crossfire?

EDIT i have 2 60hz monitors

MSI likes to hide the bandwidth specs for their PCIe x16 slots, but if you check Newegg's page for the board and click on one of the pics, it shows the slots are X16 and X8. Good for CF...

You can sell your card and invest in a single card GPU. I believe the $300 range can give a 256bit 3GB card but f I were you I wouldn't mind getting a second card and crossfiring it. I did see that card used like new on amazon for $130. Or buy a new one for like $150.

Selling and invest in a $300 card or xfire.. Either will give you exceptional performance you will appreciate.

Actually, adding a 2nd card does not double the VRAM. You will still only have 2GB available per frame rendered. Crossfire will provide an 80% framerate increase at best. Some games won't see that much. If you add a 2nd card, be sure to use the new beta driver to make use of "frame pacing" to eliminate micro-stutter. M-S is a phenomenon that occurs with dual cards in some games.

Btw, what MB do you have? If the 2nd PCIe X16 slot is only X4 bandwidth, it won't be worth adding a 2nd card.

coming from experience using a crossfire setup (7870s) i would recommend saving your money and buying a decent single card as the crossfire scaleability with games is minimal and became more of a hasstle trying to get them to work. At times i had to turn crossfire off and run in single mode to get my fps back in some games.

Unlike Inertia01, I have had excellent luck with Crossfire. (SLI too) I had 2 x 2GB HD 7870 Gigahertz cards in the rig in my sig for awhile. (x8, x8) They outperformed my 2 x GTX 660 Twin Frozrs. From my limited testing, they seemed to produce nearly an 80% gain in frame rate over a single card. At least with the games I have. Crysis 3 really performed well. There was, however, some m-s until I used the newest beta driver with Frame Pacing. The m-s totally disappeared for me after that.
I've never ever had an issue with getting CF or SLI to work. Install cards, install the driver and go. Sometimes you may have to enter the CCC and manually turn on CF for the first time. In the case of AMD, be sure to also instll the profiles after the driver. (although they state that it isn't necessary with the beta driver)
