If you got the cash the best option is to get a Mobo that supports the 7400 and your GPU , and possibly grab a quality 500-600 watt Psu and call 'er a day.I speak from experience that those OEM Mobo's are crap ,no point on straping a saddle to a dieing donkey and calling it a race horse.
I dont want to build a PC, i just want to squeeze a last year or 2 out of what i have.
I'd say i was a casual gamer, so im not looking to run everything at full whack , currently i've only come across 2 games that my CPU cant hack which are Star wars force unleashed special edition & prototype.
I know my MB is no longer suported so i have the must current bios im going to get, the last known supported processor according to the PB website was an Intel E2160.
Would i be safe in assuming that if i match the socket (LGA775),
533 / 800 / 1066 MHz FSB , and achitecure then a processor would most likely be compatable?
