I'v an intel dg31pr motherboard and now want to buy a processor for it.

Here is a provided by intel what kinda memory that motherboard would support.And seems it upto ddr2-800 (see the link plz)

And here is of all supported processors. I don't have much money to buy a quad core so I wanna buy a core2duo. Problem is im not sure which will be better for my motherboard.

2.60 GHz with 2MB cache 800 MHz bus?

or 2.13 GHz with 2 MB cache 1066 MHz bus.
what if I buy this one? 2.93 GHz with 3 MB cache 1066 MHz bus.
what about this? 2.66 GHz (lower than 2.93GHz one) with 4 MB cache(highest) 1333 MHz bus (highest)

Would these 1066,1333MHz processors will do well with ddr2-800? or upper than 800MHz will be useless?

Here is my idea....first I should look for better frequency like 3.0GHz would be the best then I should look for higher amoung ot cache memory and iv absolutely no idea about 800,1066 or 1333MHz thing... which will be better?

Gimme a lesson what should I consider first,second and third....! sorry for being soo noob :D

Short answer: a Core 2 Duo with a 1066 or 1333 FSB will work on the DG31PR and with DDR2-800 memory. The motherboard/chipset dictates memory speed, so RAM will run at DDR2-800 even if the CPU lists a higher FSB. That does not make a higher-FSB CPU useless — it can still provide modest gains because of higher CPU-to-chipset bandwidth, newer steppings or larger cache, but those gains are usually smaller than the gains from more RAM or a faster storage device.

For the workload described by (PHP, multiple IDEs including Eclipse, Dreamcatcher/Dreamweaver, emulator work and heavy browsing) the priority order should be: RAM capacity first, then single-thread CPU clock and L2 cache, then FSB. IDEs and JVMs eat RAM; when RAM is tight the system starts paging and responsiveness drops sharply. Maximize usable RAM (subject to board and OS limits) and consider an SSD for project loads, builds and VM/disk activity — an SSD often helps more than small increases in memory MHz or FSB.

Practical checklist - choose the highest-clock, largest-cache Core 2 Duo that is explicitly supported by the board and BIOS; confirm socket/TDP compatibility and any BIOS update requirements; use matched DIMMs for dual-channel operation (mixed speeds fall back to the slowest stick); and keep cooling/power within the board's limits.

Bottom line: FSB differences are not wasted but are lower priority for IDE/multitasking workloads on a DDR2-800 board. Prioritize RAM (and an SSD if possible), then pick the fastest-clocked, largest-cache Core 2 Duo that appears on the motherboard support list. This follows 's usage question and the follow-up from .

What will be the main purpose of your build? Just surfing? Or do you want to be able to game with it?
If we don't know what you want to use it for how can you expect us to offer advice?!?

Well I'm php coder, learning android development. So often I run phpED (for php),eclipse (java n stuff) and (for html and scripting) Dreamweaver all at same time...plus (heavy) surfing.

I don't play games, the game I last played far cry2 mayb. But why not checking out resident evil5 since my gf tells about it at every hour!

don't just recomen buy this...or that...plz explain a little like games need XYZ soo that processor have XZY so it would be better.....using multiple java ide need ABC and that processor has more ABC so it would better....

thanks

Did you ever decide on a processor?
