I think you meant CPU; PSUs don't care what CPU line you use them with. The only requirement is that the PSU have enough juice for the toys you are playing with. Older PSUs sometimes don't have enough current at +12V for modern graphics cards.

AMD has been pretty good about upgrade paths; you can upgrade your CPU without replacing the motherboard in many cases. Intel has not. If you have a Core 2 Quad on an LGA 775 motherboard, you are at the end of the line. Your next step will have to be to LGA 1155, LGA 1156, LGA 1366, or LGA 2011 (and a whole fleet of processors that are compatible with only one of these).

But if you have one of the better Core 2 Quads (like the Q9550 or Q9650) and a full complement of DDR2, you are a long way from being outdated.

Mine is LGA 775. I'm afraid my PSU (460w) doesn't have enough juice for these new LGAs and DDR3. Take into consideration i need to paired it with my current GTX460. So, no upgrade in near future for me.

I have exactly these only in blue and 16GB.

For $47 it's a bargain. This would be even worth sitting at the customs office for half an hour.

460 watts in a good power supply is plenty for most single-GPU setups short of power-slurping beasts like the GTX 560Ti and up.

DDR3 draws less power than DDR2 (that was one of the main motivations for developing it), and Intel has done a good job of keeping power consumption down on their new processors.

So unless your power supply is getting old-timer's disease, you shouldn't automatically assume it needs replacing.

Err sorry I meant same form of mobo to keep PSU ie atx/microatx.

Only certain small cases require microATX PSUs. The motherboard doesn't matter, except when you are using a small-form-factor case for a microATX or miniITX motherboard. Usually, cases that take a small power supply (whether microATX or proprietary) come with a power supply.

If you're using a case that takes standard ATX12V or EPS12V power supplies, then you can use that power supply with any motherboard that the case will fit. You can even mount a miniITX motherboard in a full-tower case and drive it with an EPS12V power supply, if you want to be very silly.

What to do with too much RAM? If you have to ask that, you have high-class problems.

Set up a ginormous RAM disk, partition it for your source and object trees, sync your source tree into it and build at mad speed.

Or remember the annoying loading screens and stutters when you cross cell lines in Morrowind? Gone.

Already had a set of two of those Corsair sticks, just got two more, knocked 15 minutes off the build time for the appliance I work on.

If the merchant can afford to give you 70% off, the base price is a ripoff.

Crazy prices. And here I just upped from 4 to 8 GB's for €50.
We're again at the point where new memory is going for less and less, while DDR2 prices are not going anywhere if not up. (And I wanted the more expensive 800Mhz stuff)

Games don't require more than 4GB's yet, and won't for some time. Still a bunch of 32bit users, even Win8 will have a 32 bit version. That's not half bad though, if it weren't for this, programmers would take the easy way out and just require more RAM.

Some games are starting to work better with more ram though, and even if not there's always the advantage of fighting memory leaks through having more memory to leak -> fewer crashes.

There is over-capacity among RAM chip manufacturers at the moment, thanks to more and more people buying IPads and Android tablets (with less RAM, I think Ipad 2 has 512MB RAM?) instead of laptops or desktop PCs with more RAM. Thus, RAM prices plummet at least for now.

With hard drives there seemed to be quite a raise in prices recently, apparently because some big HD factory in Bangkok had to stop due to the BKK floods. I was wondering why I could buy an external 2TB Lacie USB HD first for less than 100€, and a couple of weeks later the same item cost around 177€ in the same store. Too bad, my original idea was to buy two of them, but I wanted to test one first.

Yeah. The base price is total bullshit. I bough 1x4Gb of the same model that the OP linked for 40$ about 1-2 months ago. That would make the price for the 2x4Gb 80$ without considering that kits are usually slightly less expensive. And now I just checked the price at the same store and they are 30$. Not a discount, a price drop. So a kit like the one on amazon would be 60$. Yes, it's a nice discount on Amazon, but nothing nearly the advertised 67%.
