graphics card?

well 3k is truely low budget.
I recommend save money atleast get 5k to get good graphic card like hd 6670.
Under 3k there is only one good graphic card which is gt 620.
but not recommended, you will face legs evan in med setting low resolution
so better is collect money.
which I am doing too right now
ps-post your current configuration.

^+100 to what the guy said..
If you really want to game well, you need to spend atleast 5k
Save up , it took me a LOOOONG time to save up but it was worth it

are okay with used item? There is a gt 250 up for sale at 2.5k at marketplace here.
PS: i think giving reference to items of trade zone is allowed.

^^ it's very much allowed and do post the link

@ OP - just increase your budget by 700 bucks and get a HD 6670.

It is better to go with a GDDR5 card than a DDR3 card .... So what Ankush28 is exactly right ...

You can get HD 6670 1 GB GDDR5 @ 5.2k in Mdcomputers . One member has bought it .
