I am thinking of getting a 770, however, I am unsure which brand to go for. I've included the rough pricing of each card offered to me by several vendors. The price is only an estimate as I've converted it into USD for easier comparison (since it'll be hard for you guys to judge the price in my currency)
I'd appreciate it if anyone can recommend me one of these cards or if you think that they're really not that bang for buck, perhaps suggest an alternative card?
Note though that I've noticed several suspiciously low priced cards. (Particularly true with the MSI ones, which are called PCI express under the header in the price list I was given) I'll TRY to find more info on these cards and link them, though that might take a while.
Zotac GTX770 2GB AMP
Zotac GTX770 4GB DDR5
Gainward GTX770 Phantom OC 4GB D5 256BIT 1085MHz
Gainward GTX770 Phantom OC 2GB D5 256BIT 1202MHz
Gainward GTX770 2GB D5 256BIT 1085MHz
GIGABYTE GTX 770 OC 4GB DDR5 256bit
GIGABYTE GTX 770 OC 2GB DDR5 256bit
MSI N770 Lightning 2GB DDR5 256BIT
MSI N770 TF 4GB DDR5 OC
MSI N770 TF 2GB DDR5 OC
MSI N770 2GB DDR5 OC
LEADTEK LT-GTX770/4GB/D5 (Dual Fan)
LEADTEK LT-GTX770/2GB/D5 (Dual Fan)
So right off the bat you can safely ignore the 4GB variants because the extra VRAM will not give you higher FPS, even for 1440p (speaking generally.)
MSI is a reputed brand in GPUs so I would not be worried. There are various reviews online for you to sift through.
Here's a sample comparison I've found between the Zotac, EVGA ACX and the MSI lightning http://www.xbitlabs.com/articles/graphics/display/geforce-gtx-770-evga-inno3d-msi_9.html#sect0
a second review by comparing GB, EVGA and MSI. http://www.anandtech.com/show/7392/the-geforce-gtx-770-roundup-evga-gigabyte-and-msi-compared
All in all, you won't see noticeable performance difference, it's the thermal/acoustic aspects as well as customer service you're choosing between different brands. At these prices I would recommend the MSI N770.
