At the moment I'd say 4GB is all that's necessary for gaming, though I wouldn't do a new build with less than that. More is only needed for high amounts of multitasking (while gaming) or for special uses (video/photo editing, rendering, etc).
16GB would be way overkill unless you are doing huge amounts of video/photo editing. 8GB is way more than enough for just gaming. To be honest, if you're just gaming you should be fine with 4GB.
For latency, it depends on your chipset. For AMD chipsets you see (marginally) better performance with DDR3-1333 CL7. For Intel you're (again, marginally) better off with DDR3-1600 CL9. Past DDR3-1600 most systems won't show much real-world improvement below CL9. Unless you're trying to break specific benchmarking scores, than I wouldn't bother with getting anything faster than that.
The C300 is a great SSD. Although putting your games on them won't make the games run any faster. It might improve load times, but that's it.
Why do you need a 1200W PSU?
John,
for a 32 bit os.
2 gigs min/ and never more than 4 gigs. and actually its 3.25 gigs but you get my drift.
But..
the actual games themselves rarely use over a few hundred or if its bloaty even a gig of memory.
But there is some very good reasons for expanding your memory beyond your immediate needs when you are building a pc. Quite often if your buying something, that takes, for instance, say DDR3 memory, often its the cheapest it will ever be, right now. This is a good time to buy all you think you may ever need. No, it won't help you run crysis any faster.
But it will help you listen to music, while downloading a video, and while burning a dvd, and while surfing the web, etc. etc all at the same time.. so at $10 gig , I think 8 gigs is a really solid number to have around. Its better to have it and not need it, than need it and not have it, right? And later if you decide that you do need it, but you didn't buy it during the sweet spot of the development cycle? It now may be twice what it was, or even more, and now its no longer a value and you will get less of a return on your investment.
get 64 bit and get 6-8. So u have always enough. I'd say 6 if u work with trippel channel. 8 if u work with dual channel. Also take high frequency ram. my ram is 1600MHz. Ram in laptops for example have 1333MHz. I think.
i would put it like this:
2GB-min
4GB-fine
8-GB nice to have.
With 2GB most stuff seems playable. 4 makes it much better, and 8 allows me to leave open all of my programs and stuff while gaming.
