With GPU's you pretty much get what you pay for.
The 280x is basically a 7970. It can dip down to low 30's or less at ultra settings in the more demanding games. Its still pushing playable frame rates though most of the time and in most other games its pushing way over what you need. I would try to get better if you have the budget for it.
Looking at that price list the cpl that jump out at me are the WF GTX 770 4GB OC for $509 and the Powercolor 290 4GB for $499. Problem with that powercolor card is you have to bios update it or you will get crashes but once you do it should run like a champ. Either of these will do the job.
I saw the R9 290 4GB PCS+, but figured it was a reference model based on the price. If it is this card:

,
then it would be my choice, hands down. You're getting the same performance as the GTX 780 for $230 less and the aftermarket cooler should do nicely. You'll want to look into the BIOS issue Daleon mentioned, but that shouldn't be a big deal and def worth the savings.
I wouldn't spend that kind of money on a 770 (even a 4GB version). In the past year I've owned a 7950, a few 280Xs, a 290, 290X, GTX 670, GTX 680, and a 4GB 770. Granted, I only play a couple games (BF3, BF4, CoH1 and 2, and DayZ), but the 770s gave me almost the same performance (give or take 5%) as the 280Xs. Not worth the price difference, IMO. I got a little bit better results than Daleon mentioned with both of those cards, tho. I never dipped below 40 FPS with the 770 or the 280X in BF4 @ 1080P with everything maxed out on Ultra.
Here's a post with some of my results:

Which brings me to the 280X, question.
hi again,
Thanks alot for your advice, i will look up on the reviews. I jus realized they also have r9 280x Vapour-X too. But i want to play all the games at max graphic settings and dont want any lag while playing. not really sure if r9 280x vapour-x can do that. Do U have any idea about this paticular GPU?
The 280X is actually a rebadged 7970 Ghz Edition, not just a 7970. There's about a 5-10% difference. Then there's another 10-20% performance jump from 280X to 290 (estimated, and you also get more vram, Mantle,...).
I think the 280X is a great card at the moment. I have one in my spare/wife's PC and I have them in 2 builds I did for friends. You can basically max out the settings (@1080P) in just about every modern game and not have to worry about slowdowns.
With the prices of 280Xs at your shop, however, (cheapest I see is $439) and with the low price on the aforementioned Powercolor PCS+ R9 290 (if it is indeed the one I linked), I would say it's definitely worth it to bump up to the 290, even at 1080P. You'll have some wiggle room for newer games and won't have to worry about upgrading so soon.
EDIT: BTW, Happy 10 year anniversary, Daleon. You should ask the mods for your "Decennial" badge
