P35 and P45 quick question

[rasmusp123]

What is the difference between the p35 and p45 motherboards?
Im talking about the Gigabyte 775

1600mhz fsb instead of 1333mhz fsb, Pcie2.0 instead of pcie1, runs slightly cooler. P35 is going out of production, and soon it will be difficult to purchase them or get support for them. That's about it.

What exactly is the difference between PCIE 2.0 and 1 ?

Pcie2.0 provides twice the bandwidth. Basically, pcie2.0x16 is about the same as pcie1.0x32. The latest and fastest video cards bottleneck on pcie1.0.

^edit: you beat me to it

^More bandwidth available for PCIe 2.0.

OK thanks. so if im running a 4870, p45 is the way to go and not p35 right?

So Gigabyte GA-P45-DS3L instead of the P35

Is EP45 and P45 the same?

With the same cpu and same vga card, you will not see any noticeable difference between P35 and P45 in anything you run. P45 is newer, but the P35 boards have more mature bios. Buy on the basis of price and features.

 

[rasmusp123]

Ok, thanks for the replies guys. I made up my mind

 

[geofelt]

Don't leave us in suspense. What did you decide?

PCI-e2.0 also supplies twice the power to that of the PCI-e1.1 spec through the slot itself.

That all makes sense, and it seems clear that the P45 PCI 2.0 setup is superior to a P35 setup.

But is that noticeable in the real world? Especially since these boards are a developmental dead end (to be superseded by Nehalem), and cutting edge VGA buyers will likely have moved on to Nehalem...

Games are gpu limited, not cpu limited. As long as you're not bottlenecked in term of gpu upgrade, you're good for quite some time.

Getting the P45, since the price difference is small anyway.

and P45 is die-shrunk meaning cooler, which = higher overclock!
