Hey Guys Was speaking to Fred about this the other day as he has upgraded his pc, anyway heres my story; Right, I have a packard Bell intel core 2 quad Q8300 on a EG43M Motherboard. Now I know I am VERY restricted to what I can upgrade on this as its prebuilt (dont shoot me had it about 2 years I know I am silly), However I brought a GTX 560ti from Scan and a 650w PSU a few weeks back. I use Microsoft’s flight simulator, and have been told I am bottlenecking quite badly with this as i am still getting poor FPS in flight simulators. I've been advised that flight Sims run mostly off CPU not GPU, so how can i go about upgrading this? Would I be right in saying I could buy a case and then a CPU & Motherboard and id be able to do this?? by the way, ive looked on Scan and found a prebuilt over clocked bundle, Smart - Intel Core i5 2500K - Over clocked to 4.5Ghz - Updated August. Does this sound viable or am I way off?? Also wasn’t looking to spend any more than around £350 if that’s possible?? Thanks a lot, Adam.
