Will Zotac GTX 780 or 770 Amp run on Gigabyte EX 58 Extreme (PCI Express x16) with Core i7 920?

Hi,

This may be a little naive, but I'm a research student with a looming threat of a thesis defense around the corner, and my desktop has suddenly conked off. I have a Gigabyte EX 58 Extreme motherboard with a Core i7 920 CPU and 24 GB DDR3 memory.

I had a Palit GTX 295 GPU, but all of a sudden, I have no display on bootup. I have followed all standard troubleshooting techniques outlined in the motherboard's manual and on the internet, including taking the card out, cleaning the copper contacts with an eraser and some isopropyl alcohol, to no avail. I have also changed the PCI Express slot in which the graphics card was inserted.

While I am going to get my motherboard and graphics card checked out in a few hours, I am looking at the possibility of buying a high end NVIDIA graphics card as my work involves the use of CUDA. So I am trying to decide between 770 Amp 2 and 780 both from Zotac. I've read that PCI Express 3 cards are backward compatible, but is this really true?

Any suggestions/advice will be greatly appreciated.

Thanks in advance!
 
Solution

Yes,That is true all gen 3 cards are backwards compatible with gen 2 but the bandwidth you get is of gen2 and not gen3.But still that doesn't make much of a difference.

By the way, I forgot to mention. I have a Coolermaster 700 W SMPS. But the rated requirement for GTX 770 Amp is 600 W whereas that for GTX 780 is 700 W.

Do you think my existing SMPS would suffice?
 

Coolermaster is not a good brand for psu so I would like to have a tx 750 from corsair or seasonic one of that output which is 80 plus certified.Thank u!

I do a lot of computation (CUDA), but I won't be playing any games. Do you think I should go for the 770 Amp or the 780?

I am thinking of going in for one of these SMPSes: http://www.flipkart.com/psus/compare?ids=PSUD5XZ4JE5MZSSK%2CPSUD5XZ4YUHYSNNC%2CPSUD5XZ4XJBKDWQG%2CPSUD5XZ4JDRRC8ZY. Any suggestions?
