i have a Celeron 2.6GHZ in 1 of my computers.
I want to upgrade it to a p4 cpu with 800mhz fsb.

i have been looking on ebay and there r some reasonable price purchases.
eg. 2.8ghz 800mhz 1mb-l2 for ~60$

i would think a celeron 2.6ghz would be equivalent to a 1.8-2.0ghz p4.
wat performance gains do u think i would get from a celeron2.6 to a p4-2.6-2.8ghz(800mhz)
maybe 50% increase in games and general activities?

Make sure your motherboard/BIOS can handle the newer CPU. I know one of my PCs only supports up to Northwood (the 512K L2 cache P4s), not Prescott (the 1MB L2 cache P4s).

yeah it supports up to the 800mhz 3.4GHZ Prescott.
it can even take the 3.2EE. i dont want that though

It's tough to say how much performance increase you'll see, because the main difference is the faster FSB and bigger L2 cache. The core CPU speed is almost the same (and the Celeron is pretty much just a P4), so I wouldn't expect more than a 10-20% performance increase. I could be wrong, though!

Had to dig around for benchmark comparisons:

Intel Celeron D CPU: Budget Processors from Intel Acquire Prescott Core

I think that article may see some differences.

What was tested:

As a result our testbeds looked as follows:

* CPUs:
o Intel Celeron D 335 (2.8GHz, Prescott),
o Intel Celeron D 330 (2.66GHz, Prescott),
o Intel Celeron 2.8 (Northwood),
o Intel Celeron 2.7 (Northwood),
o AMD Athlon XP 2800+ (2.08GHz, 333MHz FSB, Barton),
o AMD Athlon XP 2700+ (2.17GHz, 333MHz FSB, Thoroughbred),
o Intel Pentium 4 2.4A (533MHz FSB, Prescott),
o Intel Pentium 4 2.4B (533MHz FSB, Northwood),
o Intel Pentium 4 2.4C (800MHz FSB, Northwood),
o Intel Pentium 4 2.8E (Prescott),
o Intel Pentium 4 3.2E (Prescott),
o AMD Athlon XP 3200+ (2.2GHz, 400MHz FSB, Barton)

thx 4 the link. pretty big improvements from goin to p4

Farcry 1024x768:
Celeron 2.8 - 35.92fps
P4 2.8E(prescott) - 62.37fps
P4 2.4C(800mhz) - 57.59fps

Winrar 3.3 KBps
Celeron 2.8 - 255
P4 2.8E(prescott) - 481
P4 2.4C(800mhz) - 402

almost 50% improvement from 2.8 Celeron to 2.8P4 prescott

Yes you will see a very nice improvement. The Northwood Celerons were complete dogs. That 2.6GHz Celeron will barely beat a 1.2GHz PIII. Seriously, the 400FSB and especially the 128k cache just killed them.
