I plan to upgrade to one of those CPUs next year so whats the better choice?

What CPU is better for overclocking & games?

My Motherboard is Gigabyte GA P35 DQ6 as in my sig with the latest Bios.

I know with P45 it would be better,but i dont want to change my Motherboard right now.

Ill change my motherboard when ill switch to an i7.

Some games are more CPU dependent for some reason. I'm in the same boat as you though. I have the 680i chipset which apparently wont allow 45m quads also. The better CPU is defiantly the Q9550 though. I know you probably don't want to hear this, but switching to a intel i5 + cheap mobo with new ram would be your best bet option, unless you could find a used 65m Extreme Edition quad.

E8400 if you are planning to OC, 4ghz is a piece of cake with good cooling on it.

If not the Q9550 is still more than powerful enough but it would need some overclocking to reach its full potential.

Most games don't support multi-cores enough to make it worthwhile yet so i'd go with the E8400 and overclock it to 4ghz.

My motherboard supports 45nm CPUs.

Well my 1st choice would be Q9550 E0 too.

Ahh i see. Anywho, if you live near a Microcenter, q9550 is only 169.99+tax, assuming you live in the US

It really depends what you are using with it, if you are using anything less than a 5970 you will be just fine with a E8400 @4ghz but with CF/SLI a quad is almost a must as duals are a bottleneck for dual GPU solutions

Yes you are right jackeyjoe its better to have a faster Dual Core than a slower Quad,but Quad is future.

Sure ill overclock it!!!


Dont know if i could get it to 4GHz with my motherboard,but i can get up to 490FSB with my E6550.

you only need 445mhz FSB to get to 4ghz (9x multi), the main problem your mobo may have is that it just isn't a good OC'er but it should still make 4ghz easily if you have a reasonable chip.

q9550, should be able to hit 4 ghz with the e0 stepping
i was in the same boat eariler this year and went with the 9550, mainly due to the fact that altho i could get a duo to a higher speed which would of been nice the quad will just keep getting more support which will put it well out in front of the duo over the coming months.

tbh i dont think you would be overly impressed with an 8400 from that cpu but the amount of stuff you can throw a quad and not be able to bog it down will put a smile on your face, i know it did with me.
If you can afford it, get the Q9550 over the E8400. They'll be exactly the same speed clock-for-clock in single threaded applications. The E8400 will probably hit higher clocks, since dual cores usually overclock slightly better then their quad core equivalents, but also because of its higher multiplier of 9x instead of 8.5x, this could help if your board isn't very good at overclocking and has issues with high FSB, which yours shouldn't.

If you only really game and browse the web and don't do any encoding or rendering, then to be honest, I'd get the E8400. It's more than enough for that, and those applications (generally speaking) don't use more than 2 cores. The odd exception to that rule for gaming is GTA IV, I know this scales tremendously with quad cores processors.
if it's up to a $40 difference, get the quad
imo the extra you spend on the quad now will save you when you come to upgrade next time as the quad will just get better as it gains more support.

forgot to put that in that ^ post :0

You really won't be upgrading anymore "down the road" though, or so I would hope, with a socket 775 chip.

Save pennies, sell current, buy i5.

In my humble opinion, I think that he would most definitely notice a difference in going from the E6550 to the E8400. The E6550 has a stock clock of 2.33 MHz with a multiplier of x7.0 and 4 MB of L2 cache, which should be 2 MB per core. But the E8400 is 3.0 GHz stock with a multiplier of x9.0 and it has 6 MB of L2 cache, which should be about 3 MB per core. Plus, being that it's a 45nm should be another, albeit small factor in the E8400 being faster and snappier. Plus, the E8400 is significantly cheaper than the Q9550.

Speaking of the Q9550, it has a stock clock of 2.83 GHz, a multiplier of x8.5 which not every motherboard plays well with, and it has 12 MB of L2 cache, which should be about 3 MB per core. But my problem with this is that it has a lower multiplier that uses a fraction, and it's quite a bit more expensive than the E8400. See below.

Actually it's a $92.00 difference on Newegg right now. They currently have the Q9550 for $259.99 shipped (normally $279.99) while the E8400 is only $167.99 shipped (regular price too). So, if this little sale on the Q9550 ends before the purchase is made, then it would make it a difference of $112 dollars.

Therefore, my recommendation lands squarely on the E8400, especially considering that the chipset is a P35.

+1

Having gone from a e6750 to a e8400 was a pretty big difference. Not only does the extra cache make a bit of difference, but the frequency you can hit makes a big difference in games.

But this late in the 775 game, I wouldn't buy a new chip at all. I'd suggest buying a used e8400 for $110 or so and go from there. Anything over that and you might as well wait to see if you can catch a deal on a i5 board/ mobo.

His board is solid. I had one for a little while and sold it to a friend. But for the time I had it, there were no problems hitting 500+ FSB. Should be more than enough for a 45nm dually or quad as long as he isn't trying to hit 4.5ghz+

I agree. In that motherboard of yours you can pump that E8400 quite fast enough for actual games so far, unless you do multithreaded stuff like Video encoding, get the dual.

I went from an E8400 CO @3.6ghz to a Q9550 @ 3.43ghz. (same FSB 400) and was not impressed by the differance it made in my games, most of the games I play only load two of the four cores, the only exceptions are Crysis and Far Cry 2 which would load the dual core to a minimum of 50% on both cores and only load to 25% across all four cores with the quad.

The duals are also easier to cool than the quads so there is that as well
