Better Graphics Card

what is your psu make and model, if its the one that came with your prebuilt box then its likely not going to run anything more than a 5670 which is okay, if you are replacing your psu I'd get a 6950 or gtx 570

Thank you so much for the reply...My PSU is just a basic 550 watt Intex unit...and i prefer to go with an ATI rather than an Nvidea.my last computer,had a GT6200 512 MB Nvidea AGP card..and you can imagine what era i am currently lost in.POP warrior within.lol....i still love the game..and would i get a DDR5 card by any chance? pardon my hardware knowledge...i haven't kept myself updated....

yeah the ram on your gpu is completely independent of system ram. If you don't want to upgrade your psu get a 5670 or else you can gamble with a higher card but I don't it will run it bc it is not a reputable named psu, such as antec corsair or seasonic... what is your monitors resolution? budget? and are you willing to upgrade your psu? if so what is the total budget for that or just a budget for a gpu if you are not upgrading your psu...

if not upgrading power supply unit:

you could try a 5750/70 (that would be the next step up) but there is no guarantees that it will work with your current psu, the 5670 will work without a doubt bc it requires very little power. Can you tell me any specs off the side of your psu? overall I would still recommend the upgrade to a quality 500-600w unit like this one:

pretty good deal right now after rebate and it will power almost all single gpu cards on the market, a power supply is just not something that it is smart to go cheap on... if you value your components...

also what resolution are you gaming at? and what is your budget for either gpu or gpu/psu altogether?

3000 INR is about 70$, he won't find anything above the 5670, it'll perform well on low resolutions, but probably run on mediums with OP's monitor

Thanks guys..I purchased the 1Gb 5670 DDR5.
