Is it worthwhile to upgrade my 4850's to a 6870? I game at 1680x1050 and 1920x1080 (I have a tri monitor setup) depending on what games I can crank the eye candy up on said resolutions. And since I have three monitors on my desk, I need to have a videocard setup that can support 3 monitors. I am not sure if I can run three monitors off of one 6870.
I am only going to game with one monitor. I use the other two when I am doing class work and really have no interests in eyefinity. I was thinking 6950 1GB, but the added $60 cost premium doesn't seem to justify 5-8 frames a second, IMO. On a side note, I just fired up BF3 and can really only play with medium settings. Will probably install 11.10 preview driver to see if it gets any better.
You will notice the difference. A friend of mine went from Crossfire 5770's to a 6850 and the jump is pretty nice and worth it.(the 5700's are = to the 4850's) Since you are going for a 6870 would be even better hope this helps.
Minus the MiR, promo code, $10 worth of newegg giftcards I found, and what I should be able to sell my 4850's for, I should only be in $40-$60 for the upgrade when all is said and done. Sounds like a pretty good deal to me not to mention I will have a DX11 card, too.
So far, so good and I am satisfied with my purchase. Went from medium in BF3 to Ultra settings (minus AA) @ 1680x1050 and get between 40-60 frames a second. I tried some other games such as metro 2033 and was able to crank up the settings much further than with the dual 4850's. I was even able to play GTA 4 without any serious hiccups with the graphics on high. The extra 512mb of memory, I believe, really helps separate the two sets of cards as well as driver support. I don't feel that the older 4XXX series really gets anything new in the form of driver support. Thanks again fellas.
