Reviews Word on the street

GeForce GTX TITAN  vs Radeon HD 7990 

In comparison, NVIDIA's "Free to Play bundle" which gives you about $25~$50 worth of in-game currency (per game) with free-to-play games such as Hawken, World of Tanks, and Planetside 2, only makes NVIDIA look bad.

Just out of curiosity, 7990 has pretty much higher everything in specs, how cloud the titan beat 7990 in some benchmark tests?
you are wrong the GTX 780 is crap and you are a nSHITIA fanboy
The AMD Radeon HD 7990 is 430GBP in UK.
are you kidding me? 7990 is far better at compute than the titan!
7990 older than titan but much powerful than titan and cheaper now
que isso tita leva um pau pra HD 7990 Ai ja e um ABSURDO !!!
9970 My ass LOOOL
Umm actually yes you can, in SLI or XFire the cards act as one, and they can use all available memory from both cards, doesn't matter that the ram is half and half, your system still can utilize both sets of video card ram.
You wouldn't say two 2GB cards in SLi/Crossfire are 4GB. The 7990 is dual GPU, so the total VRAM is cut in half and split between the two.
i have a 7770. never tried an Nvidia card yet. MIGHT get the GTX TITAN. anybody know the price at TigerDirect?
Thats not gonna be better than a 7990 though, surely?
GPU Boss isn't a reviews website, it's a direct performance and specs comparison. If you want reviews go to tom share hardware.
It's still a true 6Gb card you twit. You wouldnt say your computer isn't a true 8Gb setup because its 4Gb x2.
Hmm... interesting. I should've done a screenshot instead. Oh well, might've been a glitch then. Thanks anyways.
Look at 7990 price, it cost much less but still little better than Titan. AMD won here.
Look and 7990 price, it cost much less but still little better than Titan. AMD won here,
This isnt Speed!! The Real Speed is the GTX 780:D
Hmm are you sure Koi? This page says between the 7990 and the Titan it's too close to call. But if you do a comparison of the 690 and the 7990 the 7990 comes out on top.
I'm confused. On this page it says 690 wins, but on a similar page with the units switched places it says it's too close to call. What gives?
I think he means in a sli vs crossfire the fps "MIGHT" be better on titan
The Regular Titan scores pretty well in comparision to the 7990 which is two cards like the 690 oh and not a TRUE 6gb card as its 3gb x2
why not a GTX Titan SC vs the 7990? It won't let me compare.......
Best for me is SAPPHIRE HD7990... I like Speed !!
wait for the 9970.its gonna be a pretty badass card(8,192 gflops),coming later this year or early next year
but you spend double without double the performance, infact its alot more than double if you buy 4, you make no sense
