bro iam using pentium D 805 @ 3.gig

how far can i squeeze my cpu, iam using Tt V1 @ med low rpm, since higher rpm messes my zen

thanks for the inputs

The only way to squeeze it is to keep it cool and make sure you don't pump too many volts into it. I have used several PD 805's (3 in fact) and they all respond poorly to too much voltage. Use the voltage required and no more at any point in your OC. Also, a good MoBo really helps. Of course, it kind of goes without saying, but if you have a good MoBo, you'd be much better off with a low end Core chip then a high clocking PD chip.

so, what's its my oc enough?, or should i change it into e2180 or core 2 duo? tx.

A Core2Duo at any speed they come in will be an upgrade from what you have now. A 1.8GHz E4300 scores nearly as well in most benchmarks as a 3.6GHz PentiumD and something the E4300 even scores higher. If you can afford to get an E4500 or E6550 that would be good, but even just an E2180 would be an upgrade, especially if you go the route of overclocking the new CPU.

its the performance between oc'ed 2180 vs pure 4500, 6550 & 8xxx is wide enough?

thx.

You can overclock an E2180 and an E4500 to about the same speeds, and the E4500 will have better performance in applications that have heavy L2 Cache use, but they will be similar in performance. The E6550 will have a bit of a lead and an E8000(6MB cache versions) will have a bit more of a lead then that at the same speeds for every processor. Personally, I'd take an E4500 and overclock it, but if you want to keep a tight budget the E2180 would still be a good choice.

thanks, its the cache right?, what mainly use heavy L2 Cache use?, game or en/de coding?, if i change my dual into e2180 does it help?
because :
well right now iam forced to use 1440x900 @ my native 1680x1050 so online doesn't lag, using crt @ 1240x1024 i can do 2v2, right now iam just able to do 1v1 with medium lag (minor) @ major (mostly) @ 1680 so does changing my cpu helps?, thanks.

Games and encoding use L2 cache, although for games it depends on the game also, some games will scale up with more L2 cache, others will see just moderate improvement. Any of the Pentium Dual-Core E2000s or Core2Duos will see an increase in performance in games, but your video card is also an important factor, what games do you usually play and what video card do you have?

iam using 9600gt, 4 gb patriot viper, iam playing zero hour, company of heroes, c&c 3 kw so what do you think dude?

My 805 ran fine for months at 3.6ghz on air and standard volts.
After upgrading though, the CPU was apparently limiting 3d games.

I upgraded the processor and mb, kept the rest, and it made a noticable difference, though the E6850 is only at 3.0ghz.

so jalek what your spec?, its e2180 will bottlenecking/limit my 9600GT and if i sli (i might opt. for sli later this year) will it limit my gpus?

An E2180 at stock will bottleneck SLI, but shouldn't do too much for a single 9600GT. If you overclock the E2180 to 2.8GHz+ you shouldn't bottleneck at all for 1 card, and it shouldn't even be significant for SLI as many games use more GPU power then CPU. The PD805 will bottleneck a single card and terribly bottleneck an SLI.
