P and X intel chipsets?

post #1 of 12
Thread Starter 
Well, I'm looking for a good Intel board and im a noob when it comes to Intel parts, so..

Whats the big difference with the P## chipsets and the X## chipsets?

And is this board good for say a E8400 + 4870x2? http://www.newegg.com/Product/Produc...82E16813138122

Any board recommendations are appreciated, and the budget is kinda tight.

As in P35/P45 vs X38/48?

The X line generally have more features... the biggest being the number of PCIe lanes. The P45 only has 16 PCIe 2.0 lanes while the X38/48 has 32 PCIe 2.0 lanes. The X series is suppose to overclock better as well.

How'd you pull that off? Woulda thought you'd learned the first time

Duck stole my fire, but the main difference between P and X is the amount of PCI-E lanes. With P35, you can run Crossfire, but it'll be hindered a little bit. With x38/48, you have x16 bandwidth on each of the PCI-E slots for true Crossfire.

As I understand it, the P45's overclocking ability was its strong point over the X*8s, which have full crossfire as their forte.

I really can't offer any more than what Duckie and Gooda have already.

what about the P43 chipset?
It has 16 PCI-e 2.0 lanes and looks to be a solid OCer, and the price is right if the board is any good.

Sorry I'm asking a lot of question, I want to make sure this build is done as right as possible, and cheap lol

I dont need a quad or dual cards, so is the P43 Biostar any good for me?

Just want to add to this that with X38 I've got about close to 1000 marks more in 3DMark06 versus P35. The two MOBO's I tested were Foxconn P35A and Asus Maximus Formula. For noob I'd recommend the Foxconn P35A. It's the best board to begin with and cheap IMO.

All I can say is that the P45 is a very good, if not the best, "budget" chipset at the moment. The Biostar I45 (a P45) holds a world record for FSB. Granted, that was under a great many OC conducive circumstances. I say "budget" because if you look at the intel spec charts, the P series (the 35 and now 45) are aimed at the mainstream, while the X chipset is aimed at the enthusiast market (higher end).

The P43 is probably more of a "true," if you will, budget board, but should perform well. Biostar seems to really have stepped up their game with the P43/P45 boards. I'd say go for it.

First one was DOA.... I didn't have a PCI BIOS card then so I couldn't do any analysis.

Second one blew out when I plugged in the FDD power connector next to the PCIe slot. It took out my RAM.... I hope my CPU is ok.....
Once again...

If you don't need multiple GPUs the P43 will give you full x16 PCIE 2.0, which'll support anything you throw at it.

If you did want dual cards:
You can see here there's up to a 15% or so difference in really high performance, but its negligible for lower demands. Granted this is a P45 board, but I think they're pretty close in performance (correct me if I'm wrong).
