The core of it and memory etc.

Things have moved on so much with computers that I am confused! For someone who surfs, sends and receives emails, writes letters, uses Excel and does a quite small proprtion of photo work but not video, is a mxhike with three or four cores a necessity or unwarranted waste?

For that kind of user is it absolutely essential to have a separate video card, or will he/she succeed with an onboard card?

Finally I cannot get my head round DDR2 and DDR3.
How does one compare a processor with another pf identical clock speed. one using DDR2 and the other DDR3?

You've hit on quite a complex area, but to quickly summarise:

Multi core processors tend to improve multi-tasking and some software can benefit from them as well. Multi core processors are here to stay for a long time to come. As software is released, it is (hopefully!) written to utilise the latest and greatest technology, which means that single core processors will soon be incapable of running latest software.

There are a number of comparisons done between DDR2 and DDR3. Most of these tend to lean on specfic uses though. E.g. gaming or data processing or AV scans. DDR4 is due for release next year, so DDR2 will likely quite quickly be phased out of new PCs when that happens.

DDR3 doesn't give massive performance upgrades in most cases, but DDR3 prices are not that far different from DDR2, so you might as well use it. Unfortunately that doesn't mean that shops don't charge a premium for DDR3 though.

No, a dedicated video card may not be much benefit, but it also depends on the onboard graphics that the motherboard has. Need more specific info to give a firm answer.

The upshot is this: define the use for the new PC (which you've done), define your budget and then find the best PC for the money.

You seem to be getting confused. What is mxhike? Any old basic pc with a single core processor will surf and do Microsoft Office type tasks. What do you mean by "photo work" - editing large, high quality files with specialist software or basic photo editing we all do? Similar issues with video card - depends what you're doing, but onboard graphics can be pretty good these days. DDR2 and DDR3 are RAM memory types - not processors - but DDR3 is normally only used in video cards or high end gaming machines as main memory. You don't need that on your motherboard.

i3, i5, i7 are the latest and best cpus, powerful and efficient, i3 will suit you as it has a graphics chip included. ddr3 has taken over, 4g is a good amount for windows should be able to get a i3 based pc for a reasonable price.

Here's some DDR2 vs DDR3 comparisons.

While reading, keep in mind that motherboards have improved since these articles were written, so results may not be comparable to a PC purchased now.

Sorry for the "mxhike" typo read "machine"

Thanks everyone! From links it seems that in many ways there's not much in it DDR2/DDR3.
13 etc being the new wave, what were thir immediate predecessors? I notice that no one has mentioed AMD. so wonder if there's something disadvantaging in using>

"13 etc being the new wave, what were thir immediate predecessors?"

Not quite sure what you mean??

"I notice that no one has mentioed AMD. so wonder if there's something disadvantaging in using"

Ahhh. Well.
For low to mid range processors i don't think there's enough performance difference to start fussing about, although my personal preference is with Intel on mid range and AMD on low range.

High range, Intel gets my vote every time.

But that's me. A lot of it is personal preference. AMD do have the advantage that the processors tend to be a little cheaper.

new wave Perhaps I should have written latest or newest product

It's the '13' that was confusing me!

I'm guessing that you are asking what preceded DDR3, DDR2 and DDR[1]?

If so, the answer is SDR SDRAM.

  hatrickj 17:33 06 Feb 2010

Of dear, that will teach me to treble check whet I type. Donning my sackcloth and ashes, 13 was meant to be i3, as mentioned by citadel a few posts back.
