Well it has come time that I built myself a new system with a Core i7 and an MSI X58 board. Computer runs fast and I am happy. Perhaps later on I will get the MSI Twin Frozr GTX580 to up the video performance to play a mean game of Zuma's Revenge. HAHAHAH!! For now I am running my old XFX 9800GT. So I had a few parts left over from the last computer (Optiplex 755) and decided to craigslist out the barebones computer and use the CPU, HDD, Power Supply, Video Card (from old build) and the DVD-ROM drive. Since DDR3 Ram is so freaking cheap now ($25 a piece for 2GB HyperX blu Kingston) I decided to get a DDR3 motherboard (Gave the old DDR2 Ram to a friend) to put together a system for my daughter who is starting to do some light gaming herself. What I am wondering is the best nVidia card I can get for this system without wasting money by having it bottlenecked by an older CPU? Here are my specs: - Core2Quad Q9400 @ 2.66ghz - 4GB Kingston HyperX blu @ 1333mhz - MSI P45-C51 motherboard - Western Digital Black 1TB - OCZ ModXtream Pro 650w Modular PSU I am willing to spend some money on this thing, but I don't feel like wasting money on power that can never be used. Will the 9800GT (that I plan on replacing anyways) be as far as I can go or can I go into a 400 series card? Thanks for the answers in advance.
