I thinking of getting a new computer and needed advice on RAM as i have little to no idea about the subject. I think the top link is the best, are you in agreement? Or do you recommend a different product? I would like to keep below £170. Thanks

If you are on a budget then get the cheapest ram wth a good name. If not then the top is the best I think.
 
That site is kind of confusing. It says the corsair ram is pc 5400, but also says it's 800mhz, which would make it pc 6400.
 
The best RAM is the RAM that is going to work best in your motherboard. I can't tell you how many posts I've read about on Newegg where the problem stems from buying RAM with the wrong voltage or timings for the motherboard. I agree with the post above about going for a good name brand. Personally, I've always had very good luck with Kingston Value RAM.

I thought the PC - 6400 part was the bandwidth of the RAM and the mhz was the frequency? I also was looking for a mobo to go with my setup Intel Core 2 duo E6400 775 but thought it would be best to choose RAM first bad move?

You're correct. It's an error, it should read PC2-6400. This is 800Mhz RAM.

The Crucial RAM is fast enough if you're not overclocking. If you're in a tight budget, go with this.

Well, choosing mobo first is usually better, but I don't think you'll have a problem with any of the RAM options you mentioned. How much were you willing to spend on the mobo?
 
The last link, the Crucial Memory, is using Micron D9 memory chips, the best for overclocking. Even at DDR2-667, it should overclock past DDR2-800. So hardly for a system that doesn't overclock. ;)

If not, then the Corsair XMS2 in the second link has a good reputation also. Not sure if it uses D9 or not though, couldn't figure it out because that website is SO D*MN CONFUSING.

I'm not sure if its also the bandwidth, but the PC-xxxx numbers are supposed to coincide with the DDR2-xxx numbers. For example, DDR400 = PC3200, DDR2-533 = PC2-4200, DDR2-667 = PC2-5300, DDR2-800 = PC2-6400. DDR2 x 8 = PC2-speed, basically.

It is the effective(DDR) bandwidth. RAM uses a 64-bit interface, or 8-bytes, so to calculate the data bandwidth just multiply the memory frequency times 8 (bytes) and you get Bytes/sec.

Hence memory running at 800Mhz has a bandwidth of 800Mhz * 8 bytes = 6400 MB/s, or 6.4 GB/s. Hence this memory is also called PC2-6400 memory.

Notice that the number here is usually rounded to the neareast "nice" number. That's why you see PC2-5200 and PC2-5300 memory, for instance. The speed is almost the same, but they round one up and the other down.
 
For the motherboard i would like to keep the price low < £100 if possible, but i don't want to buy a terrible piece of hardware that will just bottleneck the rest of the system. I only really want two PCI-E ports so that it is future proof for the dx10 cards but i really don't care about SLI (it seems pretty useless as i wouldn't consider buying the same card twice.) Any ideas on good intel mobos?
