I just purchased a old asus essentio cm1630 for 75$. I play runescape and would like to run it at full graphics, it struggles hard. It has a few upgrades done to it already geforce gtx 650ti pci Express x16 gen2. Has a corsair gs800 power supply, 6gb of installed ram. Still has factory motherboard and cpu. Amd phenom (tm) IIX4 830 Processor 2.80 ghz. I would like a nice upgrade option without breaking the bank, i pretty much only play runescape. I run dual monitors off the video card. Thank you all for your patience!
