Need some advice on what CPU would be best for my upgrade. Building a HTPC upgrade for Bluray playback and HD audio out through the graphics card. I don't do much encoding, just HDTV playback and BR & DVD playing from either disc or iso rip, so shouldn't need too much power in it and want to keep temps down as much as possible. I have an Asus P5k SE mobo (S775) on the way but not sure what CPU i should go with. Options: Pentium E6500 (2.93Ghz, 2MB Cache, 1066Mhz FSB, Dual Core) Core 2 Duo E7500 (2.93Ghz, 3MB Cache, 1066Mhz FSB, Dual Core) Core 2 Duo E8400 (3.00 GHz, 6M Cache, 1333 MHz FSB, Dual Core) - 2nd Hand I won't be overclocking it and would like to use the EIST function in the BIOS to keep it running slow and cool for most of the time anyway. Will the Pentium E6500 be sufficient (it's the cheapest), or should i spend a bit extra to get the Core 2 Duo chip? No gaming or anything, just Media Centre usage, running Win7 32 bit.
