The constraint is the fact that I have a Pentium D 940 and according to the information I can find about my motherboard it can only support this now obselete range of CPUs. This as it may be, would I see any significant increase in performance by upgrading my current 8800GT to something else (I am quite drawn to the possibility of getting a HD 4870)? CPU upgrades that require a change of mainboard is sadly out of the question even though it seems that the CPU is the main bottlneck at low resolutions (My native resolution is 1280 x 1024). Thanks for any thoughts,
