Upgrade: 805 to 945

post #1 of 12
Thread Starter 
I'm thinking about upgrading my CPU from the 805

(2660 MHz default, Running at 180*20 = 3600 MHz)

to the 945

(3.4 GHz default)

which I would intend to overclock to 4GHz and beyond. I'd have a much faster CPU, with a much MUCH better FSB (from 720 MHz to at least 1000 MHz).

Just to get a feel from you guys, do you think it's be worth it?

Save that money for a board that supports C2D.

but that costs more money

If I got the 945 to 4.1 GHz, it'd be like having an E6400.

With the crap mobo I have I can run at 310x7 no problem.

310x8 = ~2.5Ghz

Any mobo should be able to at least do that, no matter how cheap. (My mobo was $45).

Well talking about trying to keep the computer I have for the most part, that's $170 for the PD 945. The mobo is no bottleneck (supports 1066 FSB) so the CPU is the limiter. Feasibly, I should hit at least 4 GHz, with a ceiling at 4.5 GHz.

To get similar results from even a C2D, I'd have to get the E6300 ($180) plus a new motherboard (about $90 for the specs I require, like gigabit NIC, HD audio, ATX)

So we're talking $270 for a new CPU/mobo combo, and that could buy me another gig of ram, which is another upgrade I'm looking to.

I'm not going to weigh in with the C2D stuff but...

yes it is worth it, the 805 is great but the 945 is much better even at stock speed. In another words, Preslers are much better than Smithfields.

I have a Pentium D 945 in my 2nd rig and it's clocked at 4.51ghz with my Tuniq Tower 120, it's fast and that rig should last for at least 3 more years.
Here's a shot of 3D06 at 4.51ghz:

Sounds good... also another question (I'm trying not to topic spam), how important is FSB speed to performance in an intel build? I know AMD's is so high it hardly matters if you are a few MHz off.
