tanishq3214,
Depending on the motherboard chipset, the best CPU's usable in a Socket 478 are the 64-bit, hyperthreading Pentium 670 ("Prescott") which is 3.8GHz, 2MB cache, about $15-25 on Ebahh and the 672 which is also 64-bit and 3.8GHz, 2MB, but is somehow higher performance, about $35-45 Ebahh. I'm not sure what makes the 672 higher performance, but it is about 50% more expensive.
Otherwise if the motherboard is too many generations past, there are 3.4GHz choices >

"it seems that the fastest 478 was a P4 Extreme 3.4GHz with 2MB L3 Cache, MO stepping, 0.13 micron. BX80532PG3400F - RK80532PG0962M (SL7CH).

So, first thing, find out the chipset your motherboard uses.
If the 64-bit (Prescott) CPU works, you might consider buying a P4 670 for about $20 and using the other $60 to increase RAM to the motherboard maximum, probably 4GB , and if there's any $$ lto be found, replace the Radeon 5450 with something like a used GTX 560 or similar.
If you can not use the 64-bit CPU, for a better investment and something with closer to current modern performance and longer-term use, you might consider selling the Pentium 4 system, adding the $80 and buying a Core2 Duo or i3/ i5 system. A budget of $130-200 buys quite a lot on Ebahh. Have a look at i3-2120 (2 cores/ 4 threads @ 3.3GHz) systems by Dell, HP /Compaq, and Lenovo. If you need a workstation, there are good Dell Precision Core 2 Duo /Quad T3400's in that upper price range.
A lot of people disregard and discard these old systems, but as many applications are single-threaded, they can be perfectly usable. As backup systems I kept an 2004 Dell Dimension 8400 with a Pentium 4 630, 3.0GHz (4GB RAM, Quadro FX570, Seagate 750GB) Windows 7 Professional 64-bit) and an Optiplex 740 with an AMD Athlon 64 X2 6000+(2cores 3.0GHz , 6GB, FX580). These systems, thanks to a good clock speed, hyperthreading, and 64-bit b/w run the older versions of all the types of programs I use, including AutoCad 2D/3D, Sketchup, Adobe CS, Corel Graphic Suite, and even the 3D modeling goes at an adequate pace- all except rendering which uses multiple cores. The 4-6GB RAM limitation does limit the number of simultaneous programs running but these work better than one would think.
