All of the following cards will fit in the 3010 MT with the exception of a few longer cards, what all of these cards offer, is ZERO BOTTLENECK ON THE 1155 PLATFORM some may require a PSU upgrade: www.newegg.com/p/pl?N=1000077...
Max ram I have been able to get going on the 3010 is 16gigs (PC1600). I tried 32 gigs of non ECC unregistered memory which I know works in several AMD systems and the board would only beep error codes. So this is a limitation of the board, not the CPU.
As for CPU, each and every one of the CPU's listed on this chart will work with the 3010, www.cpu-list.com/lga1155-cpu-...
The most powerful CPU for the Optiplex 3010 is the Xeon E3-1290v2. Why that and not the 3770k which is overclockable? It's because the Optiplex board can not be overclocked. On a z77 board, it would be much easier to take a 3770k, overclock it, do some memory tweaks, and get upwards of 4.5Ghz out of it. Since we can't do that on an Optiplex, our next step up to increase Ghz, is increase the base and turbo of the CPU which is where the Xeon chips work very well in the Optiplex. Downside, you MUST use dedicated graphics. Upside, you can squeeze just enough more out of it to beat out a stock 3770k.
