Upgrade from AMD 8750 to X4 925?

Hey I have a pretty basic ECS A780GM-M3 mobo, this is an AM2+. Looking to upgrade from a Phenom 8750 Triple-Core to a Phenom II X4 925. Would the performance boost be significant? I would be interested in an AMD X6 1045T but I can not find that CPU anywhere. Since it's AM2+ I need CPUs at 95W rating.

Or would I be better off scrapping and rebuilding a whole new pc with DDR3 AM3 and Phenom ii six core at the higher power rating?

Mainly looking to upgrade for more gaming fun, with Deus Ex and such coming out soon!

Yup that is my motherboard. Currently I have a PNY Geforce 9600GSO 768MB video card paired with it, I'm thinking of switching to a ATI 6770 1gb or higher card. Pairing this with a Phenom II X4 925 I'm hoping I can keep up with some newer games. I'm worried this motherboard's lack of using the faster six cores and DDR2 is going to hold me back or not.

Six cores wont be mainstream in games for a while yet, four is plenty, same as Ram, ddr2 is still alive enough to last you that two years as Ghnader said.

The X6 would be bottlenecked by the rest of your system, and as others have said games really don't take advantage of the extra cores. Spend the difference on getting a better GPU and you'll make the most gains there. As long as you have at least 2 - 4 GB of system RAM, DDR2 vs DDR3 isn't going to make or break it.

If you're going to replace the mother board, RAM, and GPU you might be better served to wait until the AMD Bulldozer chips are out (hopefully) in the next month or two.

I get a 7.4 on my x3 435 unlocked to x4 b35 at 3.3Ghz so the 440 should be similar if not better

The 95w AMD Phenom II X4 840 3.2GHz *Propus* is $95 with code EMCKEHF36 --- you can put the $15 toward a nice $30 HSF (the 925 is $110 - pops up from time-to-time at $100).

Despite the lack of L3 you have a 400MHz head start (and should take more volts with less heat)

Quote:
the 925 can be overclocked to about 3.36 Ghz with no voltage increase, stable, whereas it can be overclocked to 3.75Ghz with a voltage bump to 1.55V stable after a bit of research:

I think the issue (more so than anything) is the MB PWM. Not really one to build confidence in flying high :whistle: 

Even though the old x3 8750 is 95w its max spec is 1.25v --- both the C3 840/925 are 1.4v. I suspect either will be pushing the limits of the MB but should work 'just dandy' if they are qualified.

Going beyond 1.3-1.35v will certainly be at the *OP's Risk* :lol:

Maybe its my copy of windows, maybe wei is just stupid, but the cpu score stays the same at three cores on 2.9Ghz as it does on four at 3.2/3.3/3.5Ghz, meh, restoring my O/c cause it makes WoW better hehe :p
