Hello everyone. I need a little help finding out what card is best to suit my needs. Budget: $170 Looking for: Video card (and power supply if it's not enough with the stock I have) to do some gaming (not hardcore, maybe 1-2 hours a day?) Modern Warfare 2 and Bad Company 2 mainly. Powerful enough that I won't have to upgrade much for the upcoming generation of games (at least sufficient enough that I will be able to play it on low). I do all my gaming on 800x600 or 1024x768 (targets are way too small for anything bigger) My system specs (HP Pavilion p6310f): AMD Athlon II X4 630 2.8GHz 6GB DDR3 RAM 1TB HDD NVIDIA GeForce 9100 300W PSU More detailed specs here [scroll down]. I did a lot of research, but in the end, I am somewhat lost. But this is what I had in mind: HIS H485FM1GH Radeon HD 4850 1GB 256-bit GDDR3 PCI... OCZ Fatal1ty OCZ550FTY 550W ATX12V v2.2 / EPS12V S... My biggest fear when it comes to selecting and buying parts is compatibility [which is why I said I'm somewhat lost]. Like I said, I did some research and tried to learn the most, and I think I got it right when choosing that. Please correct me if I'm wrong, still a noob trying to learn. Would I need some type of cooling for the card aside from what it comes with the PC and/or card? Do you recommend anything else? (card and/or power supply) I have never changed a PSU, but I watched some video tutorials and I am confident. I've done one video card swap before on my old PC. Thank you.
