Okay, budget is $600 or so, + or - probably $50. Motherboard: Z77 Extreme 4 (RMA status as packaging so shipping out probably today or tomorrow) RAM: 8 GB DDR3 1600 PSU: 600 Watt Modstream Pro GPU: HD 4870 512 MB CPU: G530 stock (~ = to a C2D @ 3GHz) HDD: 1TB Seagate ST31000524AS Okay. I want to know what to upgrade. I am fairly happy with what I have now, as it runs what I am doing fine. I can go for a HD4870 x2 and a new PSU and be good for now but I do not know how much better it will go. Or I could get a 2500k and a good cooler, like a H80 or H100 and be good CPU wise and remove and CPU limitation from the equation. OR I could probably go for a HD6950 and be fine with the GPU and upgrade to a 2500 later and be good. I really do not know. I do not want to upgrade more than just the CPU or GPU at once as I want to see what it will do to the performance at once.
