  1. Yes gpu will support you mobo.pci e are backward compaitable.there will be no performance loss if you put pci 3 into pci 1.whats your budget specs and max screen res.
  2. PCI-Express is backwards compatible, so it will be the same within a couple percentage points, assuming it's not totally mismatched (like a 690 or 7990 in an 4x pci-e 1.1), and since you mention "budget" graphics, I see no problem.

    To recommend any card, we need to know what you "budget" is, and your system specs, primarily Power Supply (make and model) and CPU
  3. my budget is 4k to 8k.And also is Hd 7750 will be a good buy?
  4. Obviously we're not talking dollars here, so I can't comment. But the 7750 is a great low power card, not needing any extra power than the slot you stick it in, and thus the safest bet without knowing more about your power supply.

    yes dude it is good for upto 1400*900 res.saphhire hd 7750 at rs 7100 at
  6. choose between the hd7750 or the hd7770.

    the 7770 is a fantastic choice and at that resolution you can have decent fps with everything set to very high

    try out some local shops instead of online stores...they generally tend to be a bit cheaper
