Pentium D 925 (?) 3GHz or Q9400 for 'the backup' semi-gaming pc?

post #1 of 43
Thread Starter 
Hey guys,

I'm not much good with older hardware specs so I'm going to put this question to the floor. My secondary rig is running a Pentium D of some description (3GHz, CPU-Z reports it as a 925). I have a system here with a Q9400 on a dead board.

Is the quad enough of a step up to be worth buying a 2nd hand board for it and upgrading the backup system? Or am I just as well off to sell off the CPU and the rest of the parts? Google did not deliver the answers for me on this one frown.gif


Thanks,
Sam

I recall Pentium D's being pretty crappy. Basically 2 single core cpu's glued together so they never really worked together very well.

a q9400 will be quiet a bit faster than the 925.......sell off the Pentium rig and put that towards the board for the 9400

So the Q9400 is a significant upgrade? Vlasov, your suggestion is what I'm leaning toward at the moment.

Pentium D's are netburst tech like a Pentium 4.
Avoid them

a Core2Duo @ 1.8ghz would run circles around a 3.2ghz Pentium d.

The Pentium D 925 is a 2006-era Presler/NetBurst dual-core, whereas the Core 2 Quad Q9400 is a 2008-era Yorkfield/Penryn quad-core. The latter is absolutely the one to keep.

yes a 45nm quad compared to a 65nm pentium D would be a rather significant upgrade i would think. i have a pentium d 945 3.4GHz and atm i have no benchies on it since i need a new mobo it wasn't a bad chip bvut no-where near quad core standards. even C2D would be better. i'm keepin the pentium D for sub-zero wink.gif

that Q9400 is pretty much the same speed as your phenom 955 if they had the same clockspeed.
Its definitely worth it to buy a board for that and just giveaway or sell your pentium D.

My old pentium D bottlenecked an HD3650 heavily so its a waste for gaming.

The lowest life of dual core Sandy Bridge Celeron will run miles ahead of Pentium D - upgraded some 5 old non gaming computers this way. Pentium D is trash.

Thanks guys - sounds like the Q9400 will be able to make far better use of the 6870 residing in the system than the Pentium D currently does (hindsight-lol).

The RAM from the Q9400's system has already made a healthy addition to the backup system - 4GB Crucial Ballistix, 2V, 4-4-4-12 800MHz. I don't know much about DDR2 but it seems streets ahead of the mismatched crap I pulled out of it haha.
