Right now I have a GIGABYTE H61M -S2P-B3 and Intel i7 2600 and 8 GB RAM with Seagate 2 TB HDD and HD 6450 2GB. I am upgrading my graphics card.

I am planning to buy HD 7770 2GB OC or Zotac or Gainward 650 ti 2GB or Zotac 650 2GB AMP.

Which one is better and by what diffrences?
Will they fit in my motherboard?
Can I use them wiith my HD 6450?

I have 32 inch TV and hope to play games on 1900x1080 with HDMI.
I play games like Rome 2 Total War and Shogun 2 Total War.

I have Windows 7 Ultimate 64 Bit.
