I feel silly for asking this because im pretty sure I asked it once before and got an answer but cant rightly remember. But I was wondering If I am able to swap CPU's out of a OEM motherboard and if not, why so?

Is it a reputable brand, or is it an OEM/no-name? that's probably been enough for the machine as is, but if you go adding a 65w graphics card to a PSU that's really only good for 220w (off-name PSU's advertise by peak usually, not by what the PSU can continuously sustain), you could end up in a world of hurt. The corsair cx 430 is a good quality PSU that can often be found for $20 after rebates (at least lately it has) and will be plenty for a 7750 and other additions in the future. I'd recommend that at the least to go with your ram/gpu upgrade.

To expound on the previous answer, It varies widely with how new the motherboard is and what CPU you're trying to swap in. about 99% of the time you can swap in another CPU of the same family even on an OEM board, some OEM boards will let you go up a family or two from the stock CPU, but usually only with BIOS updates (which are often not available). If you're trying to go from one Northwood P4 to a faster Northwood P4, this will almost always work, but trying to put a Prescott P4 in the same board will not always work (board to board basis). It's all about what the boards chipset can/is updated to support.

I dont quite understand what you mean by " as long the OEM hasn't used a custom bios that removes support for some processors, as it does happen " sorry if i sound ignorant on the subject anybody.

Basically, if a processor was made at about the same time as the one you have, but performs better, it's probably the same 'family', or architecture it was fabricated with. Sometimes even within the same family OEM's will put code in the BIOS that will make the PC refuse to work even if it should be able to use a certain CPU.

It almost sounds like id be better off and safer just not updating my CPU and buying a new motherboard.

Well then ill just update my RAM by 4 GB's and get a Graphics Card to fit my computer, I was told a Radeon HD 7750 1GB DDR5 will be compatible with my computer the way it is but am not to sure. If you got any good ideas for what Graphics Card would be compatible for my system, id appreciate any info.

Is there any Graphics Card and RAM I could get without having to upgrade my PSU?
