I have an EVGA X58 mATX board (121-BL-E756-TR) with all the power i need except CPU. The i7 920 CPU that's in it lacks the AES instruction set, and I could really use the extra instruction set for all the encryption/decryption I do plus batch photo processing. When exporting/transforming photos, it uses all cores at 100% and I'd like to get more performance out of it. (Disk i/o not an issue with my raid.)

Are there any drop-in replacement CPU for upgrade? I'd prefer not to upgrade motherboard if I can avoid it. I guess what I want is a CPU support list, but I didn't find it on EVGA's website....

I say get a used i7 970 or replace the motherboard / CPU and probably ram (if your ram is > 1.5V) with a haswell based i7 system.

Something like a L5639 might be interesting. It is a low power 6 core Xeon CPU that drops in to any X58 board. It is built using the newer 32nm technology, similar to the Core i7-970. They overclock like crazy if your board lets you adjust the BCLK. They also include the AES instructions and best of all, they sell on EBay for about $80 including shipping. Good luck finding an i7-970 at that price.

I'd go for an X5650/5660 for the same price, higher stock multi if your board doesn't like 230+ BCLK. My X5650 did 4.2ghz no sweat in my Gigabyte UD3.

I just checked my mobo, and I saw "REV 2.0" on the bottom left corner. So, I'm optimistic that I can do this in-place upgrade. I may bump to the X5675 just to have all glorious 3.0 GHz. :)

Thanks for the tips, everyone.

i7 920 easily overclocks to 3.5Ghz without vcore increase or just get xeon x5650 on ebay for ~$70 shipped
