I am planning to upgrade my pc step by step. As it does not have any gpu i am planning to buy a gpu first. I was thinking of buying nvidia Gtx 560ti but there are rumors that kepler is coming soon. So what should i do. should i buy the fermi or wait for kepler. There is another problem , it seems nobody knows in which port kepler will come. I mean will it be available for Pci-express 2 or it will come in Pci-express 3. i really do not know what to do.
Its pretty much set in stone now that the first keplar cards (GTX 670ti & GTX 680) will be out in april, so if you dont mind waiting till then i would defintely recommend it as you should be able to take advantage of either the performance upgrade or the price drop in the 5 series cards.
I would wait for kepler if only just for a price drop. that said, I have no clue when kepler midrange cards will be out, but the radeon 78** cards should be out soon for $250ish, and I would just go with a 7850. judging by the paper release benchmarks here, it should run much faster than a 560ti
guys you did not answer one question that is the port. I think everyone[almost] who have i5,i7 or whatever cpu, they have a pci express 2 port. So if kepler comes directly to pci-x-3 then they have to change their motherboard at least. but if they do not change mother board how much will they suffer in performance. now pci-x-2 has a big room for bandwidth. No single cards that are available now can half utilize it [correct me if i am wrong]. And we know kepler is not going to be 3 times more performer than todays card .Then what is the reason of implementing pci-x-3.
Huh? I answered this in the very first post. Let me repeat:
PCI-e 3.0 cards will run just fine on PCI-e 2.0 mobos; they will just run at PCI-e 2.0 speeds, which is fine because not even the fastest cards are bandwidth limited by PCI-e 2.0. Nobody has to change their motherboard to get a new GPU (maybe if you had an old PCI-e 1.0 board, but those are ancient now). Even crossfire 7970s do fine on PCI-e 2.0.
The reason of implementing PCI-e 3 is to prevent things like quadfire or quad-SLI configurations from being bandwidth limited by PCI-e bandwidth. It's basically a future proofing of the technology, nothing that is necessary for today.
Thank you Bigmack i understand now. So everyone who got pci-x-2 need not worry about the upcoming kepler even if it is pci-x-3.
