Thanks it did. i still need to decide what graphic card i am buying. is it possible someomne can give me few more choices and what is best? thanks
Oh, yeah was supposed to get back on that. Since you are gaming on 1080p, the 560Ti seems to suit you the best and it's overclockability means it is quite future-proof. Although, I'm not too sure of the price, they vary by brand and time.
Two situations:
1. If your budget allows, I would recommend going for the 560Ti but make sure your PSU can power it. a good 500w and above would do fine.
2. If your budget does not, the 560 is the one to go for. It may be weaker but still a darn solid card which won't let you down.
And yes, I realise your budget is 250$ but, this is in case you want to spend less and keep that hard earned cash of yours on other things.
When it comes to overclocking, both card fare quite well. Even if you choose not to, that's ok, they're still good and will haul considerable workloads. But, keep in mind, the 560Ti is known for being OC friendly.
Regarding the newer core 560Ti, I would suggest letting that one go. The price, when just released, may be out of your budget and there is no concrete release date yet.
Conclusion? With your budget and resolution, all signs point toward the 560Ti.
P.S. If you have an SLi ready motherboard, bang put any of those in a pair on watch it fly. Oh, and sorry for the long post.
