Yep, did some massive researching.. need to make a a value of my money, and consider this a long-term choice. Remember, budget is important. I'd rather have a $80 card where I could run GO fine etc, unless the additional money spent is worth it - state below.
I couldn't find or think of any other GPU's around that price range... if I'm missing one someone let me know, but hopefully theres a better insight now on this . Thanks for everyones help, please try to justify your answer also! =]
I'd get a 280, 560, and a 7770, if the choice was mine to make. I'd get the 280 because it was a serious enthusiast card during its time however its prime has long since past it doesn't enjoy current driver support and technologies, and is overtaken by current entry-level gaming cards such as the 650 ti. The 280 is also hotter and consumes more power than contemporary cards of similar performance.
Now on to the 560. The 560 is a great card just a generation behind, the only draw back I can think of is its power draw and heat. Otherwise I'd find the card a very attractive choice.
The 7770 is something to consider as well. The 7770 beats nVidia's 550 ti and is a great performer at resolutions below 1080p, and has a significant OC headroom. I was thinking of purchasing this card as well but its lower memory interface (at 192-bit) and 1gb of video memory gives me thought.
I narrowed it down for you.. Now, if you can get the 560 at its current price, I'd go for it, but charts place it at a tie with a 650 ti. If you can afford the 650 ti, that would be a better choice, but what puts me off is that you can't SLI the card.. buuuut, there are persistent issues with multi-card setup with entry-level gaming cards.
Edit: Whoops. Disregard my comment for the 560 SE, I forgot about the SE part. ARICH pretty much nailed it.
