Summary: Bought a used E5400 CPU here on eBay. OC the CPU to 3.6GHz stable on a Gigabyte P35 Socket 775. I actually downclocked it a little bit to 3.4GHz because I don't play many games that need this power. Great purchase for under $40.
The perfect processor line for computer users on a budget

Summary: I like the fact that Intel took their Pentium line out of retirement. With the Core and the Celeron, you, either, get super expensive or super slow. The Pentium allows for the balance of speed and cost. What's more, this has a duel core. On a side note, this is 64-bit ready.
Summary: I had a an E4xxx cpu in a machine that acts as a file server in the garage. Since it is on 24/7 and i upgraded my network to gigabit Ethernet, i decided to upgrade the cpu with a E54xx cpu. This particular model also has virtualization enabled, but that's not necessary for a file server.
Summary: Last Christmas I purchased an Acer Aspire M1641 from local BX/PX. Came with an Intel E2200 Pentium CPU. 2.2 Ghz Dual Core. 1Mb L2 Cache. I upgraded to the E5400 2.7 Ghz Dual Core. With the faster speed and 2Mb L2 Cache, My PC runs much better than stock.
