I want to buy a gpu and will run it for 1year maximum...So suggest a good GPU which can play new games like MW3 without any prob with that resolution.
Here are my current specs :
17" CRT (1024 x 768 )
amd athlon x3 445 rana 3.1 ghz
2x2gb 1333mhz RAM
asus m4n68t-m le v2 mobo
250w psu
You need to change your '250Watt PSU' before you can change the GPU.
Also do mention your budget.
Get a Sapphire HD 5670 along with a Fsp Saga II 400w as your current power supply is too less for this GPU.
@op please post your budget first, so that our members can give you accurate suggestion
@hari11 just go for components I mentioned in my earlier post. Will cost you a bit less than Rs.8000 total.
You mentioned you'll run it for 1 year maximum. Now the question is after this period of a year, will you give up PC gaming or buy a new better PC?
If no more games for you, then buy what thetechfreak suggested.
If you'll be buying a new PC then get something of the likes of HD 7850 and upwards with Seasonic S12-ii 520 or Corsair GS600. While this might be overkill for your current config, it'll be very essential for a future build. So rather than wasting money buying the same stuff twice, get the better stuff from the beginning. I suggest this as you mentioned budget is no concern for you.
Guys budget unlimited means that he doesn't know how much will a good graphics card cost him suitabe to his requirements.
No need to recommend an HD7850 for gaming at 1024x768 however future proof is it gonna be. Its simply a stupid decision to buy that card and the result will be an unbalanced rig with loads of bottlenecks.
Here is what you should get for a medium budget -
An HD6850 + Corsair CX430v2 costing a total of around 11k
For something under low budget -
HD6770 + Corsair CX430v2 totaling around 7.3k
These combos will serve your purpose well and you can easily game at 1024x768 for coming 1 year.
If you plan to upgrade to an HD monitor later, you will be better off with the first combo I suggested.
