Hey guys! I have a computer that i bought in 2008 and the specs for my pc are CPU: Intel Core 2 duo E8500 MB: Asus p5q-e GC: ATI Radeon HD 3650 PS: Corsair 450W CMPSU-450VXEU Ram: DDR2 4GB PC8500 Corsair XMS2 Domina,(2x2048MB)EPP HDD: 1TB Samsung Spinpoint F1 HD103UJ Cooling system: Thermalright Ultra-120 Extreme + Noctua S12-1200. And 3 Nexus 120mm in my case. what i had in mind was upgrading my MB, CPU, RAM and HDD. here are the specs Intel Core i7 2600K 3,4GHz Socket 1155 Box Asus P8Z68-V Pro/GEN3 Intel 320 Series 2.5" SSD 80GB Corsair XMS3 Vengeance DDR3 PC12800/1600MHz CL9 4x4GB Samsung EcoGreen F4 HD204UI 32MB 2TB I want a fast computer that will still be good enough for 2 years so thats why i have the ssd hdd and a 2TB hdd for storage. I do not play games on my pc but i have it on 24/7 and i use it for mostly surfing the web, watch HD movies and utorrent running 24/7. I feel the system i have right now is not keeping up with what i do. I also use Mathematica and Catia/Solidworks sometimes. Do i need a new graphic card as well? Do i need a new Power supply? My price range is at 800$ Btw, i live in Sweden so the prices are probably different here. So can you give me some advice if this is good or bad?
