Hello, I'm trying to upgrade my friends computer. I'm not sure what kind of motherboard(thus I don't know what gpu connection to get) it uses. It is an old Dell inspiron 530S. Just looking for a small (and really cheap) gpu that can let him play stuff like counterstrike and tf2. The integrated Intel graphics don't cut it.

Thanks for any help.

Is this the one he is trying to upgrade? http://www.dell.com/us/dfh/p/inspiron-530s/pd

If so, that 250W PSU will be cutting it on most modern graphics cards. From Googling it, it looks to have a Pentium Dual Core, which really is not meant for gaming. The case looks to be a slim case as well which will really limit your options further. How much is he willing to spend?

From both the http://www.dell.com/us/dfh/p/inspiron-530s/pd and the http://reviews.cnet.com/desktops/dell-inspiron-530s-desktop/4507-3118_7-32486101.html has it listed as having a 250W PSU.

@OP you should have your friend check to see what PSU he has.

The PSU he linked was an upgrade for the 250W stock PSU.

Ah very well, I misread that. My mistake.
