In my opinion you'll be more than OK with mid-range card like the 660GTX or its AMD equivalent the HD7870 and possibly even lower.

At 1366x768 you can play most games even at high settings. Any other card more powerful would be a waste of money on that resolution because you won't be seeing any visual difference.

1366*760 resolution you would be fine with a 7770*6850. If you don't plan on upgrading your resoltuion then I would not see a need to go any higher than a 6950/7850. You mention only amd cards so I assume you only want amd cards.

I'm sure you will find some money to buy a new monitor down the road so thinking in perspective if you can the 7950 is a good investment. For now a 7850 2GB is enough.
