hi... i am looking for a graphics card that falls in my budget of $70. considering it, i have short listed 2 options, nVidia 9500 GT & ATI Radeon HD 4670, both 1GB, DDR2. apart from that, my pc has 2 GB DDR2 ram, with core 2 duo 2.8 Ghz & lots of hard disk space, Motherboard Intel DG41RQ, PSU is ATXP4 with 450 watt (thats what it says).
i would like to mention here that i have successfully played good graphics games like COD MW2, Crysis and GTA san andreas, WITHOUT the graphics card, my system already runs games with good graphics, and adding an above average graphics card would fulfill my requirements. what do you think? i would like to play Assassin's creed 2, COD Black Ops & MW3, NFS Shift etc.
so which card should i choose? will that one run on my pc without upgrading anyother hardware (like PSU)?
However you do need to bear in mind that the test systems used in the reviews are designed to be powerful enough that no other components will constrain or hamper the performance of the card - so they get a true read on the cards ability. Your system likely will not be as strong and so your performance might not equal the level in the review.
You can find some good information about video cards at upgradevideocards.com. Note they have a page on low end cards – primarily for HTPC but that also support the low end of gaming – and the HD 5670 is one of the recommended cards.
Would you please look further for make and model of your PSU. “ATXP4” probably just means it meats the ATX standard for PSUs and is designed to support Pentium 4 processors. It would be good to confirm that it is a good model or you could have some problems with the HD 5670 which requires 400w. If you are not sure about how to do this or need more info about power supplies for video cards, the site linked above has a page about systems requirements that addresses power supplies – see about the middle of the page:
