In short, the only processors that would fit your needs and the socket 775 are Core2Duo processors, the predecessor to the Intel iCore series.
Based off of newegg, the only choice for you is the Intel Core2Duo E8400 Wolfdale @ 3.0 GHz. Unless this is a temporary CPU you'll be using until you get a new computer, then you could go with a Pentium E6800 for $100, but it won't be anywhere as good as the E8400. FYI, the LGA 775 platform is an obsolete platform the past 2-3 years when Intel released the i3, i5, and i7 series back in 2008 (i7), 2009 (i5), and 2010 (i3). If you want to get one of those processors, you will need to get a new motherboard, and when you do that, typically you'll want to buy new RAM as well since you're using DDR2 and the best performance would be DDR3. This is one of the reasons why I haven't upgraded my CPU for so long because my next upgrade would involve the CPU, Motherboard, RAM, and GPU, which would be around $700 for the parts I want, minimum.
