LGA 775 CPU Upgrade

I want to upgrade my CPU to the best CPU possible for my MOBO

My motherboard is currently the BIOSTAR P4M890-M7 TE
http://www.biostar-usa.com/mbdetails.asp?model=P4M890-M...

Description about the kinds of processors I can use are as follows
• Processor:
Socket LGA 775
Supports Intel Core 2 Duo/Pentium D/Pentium 4/Celeron D/Celeron 400 Series Processor up to 3.8GHz
Supports FSB 533/800/1066MHz
Support Intel Hyper-Threading Technology
(It is recommended to use processors with 95W power consumption)

I currently use an Intel Core2 Duo E6600 @ 2.40GHz
http://www.cpu-world.com/CPUs/Core_2/Intel-Core%202%20D...(BX80557E6600).html

I was thinking of getting Intel Core2 Duo E8600 @ 3.33GHz (I think this is the best for Socket LGA 775)
http://www.cpu-world.com/CPUs/Core_2/Intel-Core%202%20D...(BX80570E8600%20-%20BXC80570E8600).html

Here's a comparison of the two
http://www.cpu-world.com/Compare/595/Intel_Core_2_Duo_E...

However, the E8600 has a bus speed of 1333MHz while my FBS supports at max at 1066MHz

The best option for 1066MHz is the Intel Core2 Duo E7600 @ 3.07GHz
http://www.cpu-world.com/CPUs/Core_2/Intel-Core%202%20D...(BX80571E7600%20-%20BXC80571E7600).html

The comparison of the E6600 and the E7600 are as follows
http://www.cpu-world.com/Compare/594/Intel_Core_2_Duo_E...

So should I go for the E7600 or the E8600 and why?
Also are there better processors that I should consider?

Please don't suggest me to use my money on building a whole new rig instead.

You can't use the E8600 because of the different bus speed. It just will not boot your system.
Whether the E7600 is a worthy upgrade can really only be answered by you. How much is a 25% or so improvement in processing speed worth to you?

I've owned two of those boards and the best thing you can do is get rid of it and never look back. Even with the same cpu and a newer board you will notice a performance improvement as this board isn't even dual channel but 32bit single channel that makes even Atom's memory i/o performance look good. As for the cpu don't waste your money. Just save for a little longer and buy a 1155 board, a kit of ddr3, and a cheap Pentium or i3. The difference will be night and day even the most basic tasks.

As for the two that I owned both eventually failed.

Will my motherboard be able to support quad core? I dont think quad core was invented yet

The board might manage 1333 fsb but the chipset and it's cooler are very poor. I've owned two copies of this board and it is pure crap. Not even worth buying a new cpu and it even bottlenecks lower end cpu. Just to say how bad it is that not even a P4 can perform as well as other builds with a different board. Most now days can't even begin to think how bad 32bit single channel memory controller is.

No it won't, you would have to be pretty dumb or crazy to put one in and expect the board's power vrm to hold up and for 9xxx Quads chances it won't run at full stock clocks due to the chipset.

lol thanks nforce4max. jw why did you get two of these boards back then if they were so bad? Also where can i read about 32bit single channel and dual channels.

You can find deactivated posting for this board on newegg through a google search. I bought these boards back in 2007 when I was still a noob, plus they had ide support when I was still using older drives. The board's power vrm can handle around 65-75w but any more will only shorted it's life span and even then it can drop dead when you least expect it. The first one that died simply locked up and I hit the reset switch and it never booted up again let alone power up. The second board became very unstable even with a celeron 430 so it had to go. So I suggest that you just forget about 775 and move on. The newer boards and cpu(s) are much faster and are great quality. 1155 SB based Pentium or i3 will fit your needs nicely while giving you the best options for the most modern cpu tech out there.
