I am thinking it is time to upgrade my 8800gts 640mb now, as it is getting on a bit and is being left a long way behind by some other cards out there. My spec is in my sig and i mainly play source based games and call of duty series games. And i am looking at spending around £150 on a graphics card that will last me a year till next upgrade. and suggestions would be great, and also i need to know whether a 520w power supply would be able to cope with them
