My current PC is getting a bit long in the tooth and I want to build a second one but get what I can out of this one and use it as a secondary rig in the office so the boys can play together and/or I don't have to kick them off when I want to get something done. My thoughts are new GPU and maybe a CPU cooler and overclock. Overclocking was the original plan but I never bought a beefy cooler. Intel Q6600 (step G3 I think) Azus P5Q-E MB 8GB corsair ram 2x4. Can't remember the speed Radeon 4850HD TOP GPU Samsung 240 SSD various other storage drives Mid level corsair 650w power Antec 1200 full tower case with a ton of fans. My boys play Minecraft (and mods), Terrairia, Starbound and a few other such diggy hole games, but are now 10 and 13 so will be expanding their horizons shortly. I will build a new one soon just getting caught up on all the current tech. Any suggestions on a GPU that will not be to much for the CPU handle? Was thinking a $200 or so GPU and $50 for a cooler. Or is the thing so old I am better off building a budget system for that case?
