I'm using an HP Pavilion P6120f 64-Bit.
Will I be limited to the speed of the USB 2.0?
Any tips?

Should work fine. I was running 40 Block erupters off some 10 port 3.0 hubs plugged into 2.0 ports on the PC. I found the 3.0 hubs were actually more reliable when plugged into 2.o ports than when I plugged them into the 3.0 ports. To get them all to work at once though I ended up having to recompile one of the drivers to make the detection timeout long and get them all working at once.
That said you can never know for sure until you try. The Raspberry Pi for example doesn't work with 3.0 hubs at all for some reason I don't fully understand.
