That seems very good. as iv never ran anything on ultra with my 550ti, let alone the 460 i once had. When are the 8000 series coming out? Would a 7870 vs a 8870 be better? Should i save up and keep saving up untill the 8xxxx series are released and go to town? I havent really looked into the market when Gfx cards first come out. what would the 8870's and the 8950's price start at, if you could guess.

if you are on a tight budget get the Sapphire HD 7870 XT with Tahiti LE chip. HD 7870 Tahiti LE is 8 - 10% faster than the regular HD 7870 at stock. at same clocks around 12% faster.

but as suggested above save up the extra money and get the HD 7950 boost

http://www.techpowerup.com/reviews/Club_3D/HD_7870_jokerCard_Tahiti_LE/

HD 7870 - 53.8
HD 7870 Tahiti LE - 59.2
HD 7950 iceq x2 boost - 67.5
HD 7870 Tahiti LE(1210 Mhz) - 69.8
HD 7970 Ghz - 78.9
HD 7950 iceq x2 boost(1210 mhz) - 82.9

HD 7950 boost is 15% faster than HD 7870 Tahiti LE at stock and close to 20% faster at same clocks. HD 7950 boost is 25% faster than HD 7870 at stock and 30% faster than HD 7870 at same clocks.

With only a 500w powersupply, i wont be able to crossfire anyway, now that i think about it. a 7950 would look like the best bet, but hell, lets keep the topic going.

I have an i5 3570k, pairing up with the 7950, how would it preform on BF3 on ultra at 1080p, and how would it run with duel monitors? do i need the two same monitors to play the same game? or just the same resolution?

You cannot play fps games in 2 monitors. the crosshair will come at the place where the monitor bezels meet. you need 3 monitors minimum. the centre monitor will have the crosshair at its centre. the 2 monitors in the side will provide peripheral vision.

what power supply do you have and how many amps does it have on +12v rail. you need a high quality 500 - 550w psu with atleast 40A on +12v rail to be safe if you are overclocking both the 3570k and HD 7950 with voltage increase.

You would run BF3 with Ultra settings no problem with a 7950 and any reasonable CPU produced within the last couple years. With the recent driver updates, I would say 50+ FPS all day long.

Also, you could run the game on 2 screens, but it would be unplayable with a FPS game. Yout sights would be split in half by the bezels.

ahh well buying two more monitors is out of the question for me right now. alrighty, well its nice to know that i wont be gaming on a couple screens in fps. One monitor is enough for me, for now. um, its 500w, Cooler master extreme power plus. umm, a 12V1 and +12V2?

If you're only going to do single monitor gaming, you don't really NEED a 7950, but it's nice to have in the long run. With a single monitor in mind, a 7870 would last you at least 2~3 years without having to upgrade. A 6970 (released late 2010) is an equivalent of a 7870 and most of the 6970 owners have no intention to upgrade anytime soon.

Just to put it to perspective, my 7950 can max out many games and run BF3 in Ultra/High with a 3240x1920 res (3x 1080 monitors in portrait).

My advice: if you can't afford a 7950, 7870 will meet all your needs for a very long time, if that $50~100 would take you a while to save up, it's not really worth it when you're maxing out 95% of the games out there with a 7870.

with dual 12v rails of 18A each but only 30A combined across both rails your psu is not good for a HD 7950. restrict yourself to a HD 7870.
