Current setup: Intel Core i5 750 2.66Ghz (Lynnfield) (Socket LGA1156) Gigabyte GA-P55M-UD2 Corsair 4GB (2x2GB) Dominator DDR3, PC3-8500F (533) XFX ATi Radeon HD5850 Samsung 256GB SSD 830 Notebook/Apple Series SATA 6Gb/s KIT with Norton Ghost - (MZ-7PC256N/EU) Corsair hx 520W PSU The max resolution I can game at is 1920 x 1200. I do NOT want to overclock the CPU/ GFX card as in my experience it always leads to stability issues and crashing especially in Battlefield. I was hoping maybe just a ram (4gb more) and GPU (280X) upgrade would be enough to max the game at 1920 x 1200. I was hoping to do this within a budget of £300: -would I be heavily bottlenecked by my CPU? If yes, could I upgrade my CPU only to the highest possible with my motherboard without having to upgrade everything? -would my current PSU be able to power the new GFX card without any probs? Alternatively (the route I ideally dont want to take) would be a full system overhaul including MOBO, CPU, RAM, GFX and may require PSU also.
