I have, for a long time, wanted to build a gaming computer for my children. Mostly so they will stop using mine, and so they can play with me rather than near me. My brother has offered his wife's five year old machine as a starting point. The only things he can tell me about it is that the graphics card is defunct, it has four gigs of 1066 memory (at least that's what the label on the sticks read), and the motherboard says socket LGA775.

The question I have for you nice people is this: I will more than likely want to install a contemporary processor in that socket, so what should I look out for? There are scores of chips that fit it, and I'll use my budget as the most discretionary tool for choosing. But I don't want to choose one that will a pain in the ass with compatibility, BIOS, or whatever.

Can you help?

Anyone with experience with such situations (five year old mobo, brand new CPU), speak up!

Thanks in advance.

The "beefiest" CPU that you can fit into such a socket is a Core 2 Quad Q9650 or a Xeon X3370 Yorkfield. It is slightly behind an average contemporary i5 but faster than i3 if we were to believe what the benchmarks say. But if the motherboard can run such a CPU is a different story though, it depends on whether the BIOS can recognize it. A suggestion is to look for the latest BIOS update and CPU compatibility charts which are usually found on the motherboard support page of the vendor's website (such as Asus, Gigabyte, MSI and so on...).
