Upgrading to a new single GPU

post #1 of 9
Thread Starter 
All,

I currently have crossfired HD 6870s and was thinking of upgrading to a single GPU. I have a budget of roughly $400.

I was looking at reviews of the GTX 770 and really like what im reading. Any suggestions? Will I notice an improvement?

Of course you will. The 770 has a kickass price too for its performance. You could also always go for a 7970.

OP you could definitely get a GTX 770 if you want. EVGA ACX is one of the best

but there are some excellent bang for buck cards out there. you can consider getting a Sapphire HD 7970 OC(1 Ghz) for USD 318 (298 after mail in rebate)

http://www.newegg.com/Product/Product.aspx?Item=N82E16814202008

another option is Sapphire HD 7950 boost for USD 260 (240 after mail in rebate)

http://www.newegg.com/Product/Product.aspx?Item=N82E16814202026

both these cards on average can overclock to 1100 - 1150 mhz and are faster than HD 6870 CF. at the same clocks HD 7950 is 5% slower than HD 7970. HD 7950 at 1125 mhz matches HD 7970 Ghz(1050 mhz) perf.

http://www.hardocp.com/article/2013/07/02/msi_n760_tf_2gd5oc_gtx_760_overclocking_review/5

http://www.techpowerup.com/reviews/HIS/HD_7950_X2_Boost/28.html

HD 6870 - 55
HD 7950(950 Mhz) - 100
HD 7970 Ghz - 115

HD 6870 CF in best cases is around 1.8x HD 6870. on average across many games its closer to 1.6x. so you will see a nice perf improvement even with a stock HD 7950 boost. overclock HD 7950 to 1100+ mhz and you will see 40 - 50% higher perf.

You could probably sell your 6870s and get enough or ALMOST enough for a 780 biggrin.gif

If not the 770 and 7970 are both great cards for the price right now thumb.gif

I did some research and decided to go with the XFX Black edition DD 7950. Its close enough to a 7970 when OCed and I will end up saving quite a bit over the 770 or 7970. Im not an enthusiast overclocker so the voltage being locked at 1.3v is fine with me. I'll just be happy to be down to one GPU.

Thanks everyone for the info.

EDIT:

I just cancelled the 7950 order after looking at the Sapphire HD 7970 that Rahgu78 posted. My question is, since the XFX 7950 and the Sapphire 7970 are essentially the same price, is it best to just go with the 7970?

Ofc, the sapphire is far better than the xfx. For the same price you get a faster card, better cooling and lower noise.

Thanks. Sometimes the numbers look better when compared but actual performance isnt necessarily better, sometimes its even more or less the same.

Thanks. I will certainly get the 7970.
