hi, i have Celeron 800 Mhz on my PC. the mother board Processor support is up to Pentium 3 ( 1.0 Ghz @ 133Mhz FSB.) is it good to upgrade the processor to 1GHz or stay with this one. is there any speed enhancement while i upgrade??

other then the 200mhz increase the pentium 3 1ghz as a larger L2 cache which should help alittle bit in preformance, but nothing big. Adding another 256mb of ram would help more so then adding that processor. But if you have the money to add more ram and a processor upgrade then yes you should see an ok improvement overall.

What speed is your current ram? If you upgrade to that Pentium 3 with the 133 Mhz FSB you will need PC133 SDRAM. If that is what you currently have all is well. Compaq Presario SR1720NX Desktop Computer AT&T SBC Yahoo DSL Home Linksys Router/2 computers

Should be a nice boost, UNLESS you have some slow-arse graphics card in there (most Celerons of that time used the ridiculously underpowered i810/815 or SiS integrated graphics, and had no AGP slot to 'counter the effect'). The P3 boasts these advantages: -256KB L2 cache on Coppermine versions. This is double the amount of a Celeron. Cache greatly enhances performance If you can find an "S" Pentium III w/FCPGA-2 adapter on ebay, get that. These "S" PIIIs have 512KB of cache, are based on the excellent, cool-running Tualatin core, and the 1.4GHz version performs on par with a 2.2GHz P4. -All P3s have 8-way set associative L2 cache; Celerons are only 4-way set associative. -The P3 has a faster bus. 133MHz, vs the 100MHz on the Celeron. This is great because the chips based on the P3 architecture (including your Celeron) were always severely bandwidth starved, so every little MHz tacked on to the FSB helps quite alot. Of course, if you don't upgrade your RAM and/or if you're stuck with the horrendous integrated graphics most cheap Celerons were supplied with, I wouldn't bother.
