I don't normally go over it, but my PC pretty much blows.
I recently did some small modifications (Back around the holidays).
Old PC: Intel Core2Duo E4400 [original] (2x2.0GHz), 3 gigs of DDR2, 320 gig 7200 RPM 16mb cache SATA drive, 80 gig 7200 RPM 8mb SATA drive, eVGA 8800GT (AKIMBO), Sound Blaster Audigy 2ZS, Asus P5N-E motherboard.
Current PC: AMD X2 6000+ (2x3.1GHz), 8 gigs of DDR2, 1TB "Green" SATA 3 (6gb/s) 64mb cache drive, AMD Radeon HD6870, Asus M4A77D motherboard.
A little give and a little take. My new drive is ultra slow, but will mainly act as a storage drive. It can make gaming quite a pain at times. The CPU, while it is an upgrade, is still very limiting in it's ability to play newer titles. The video card is solid and will probably be carried over and possibly placed into a Crossfire config in my new PC.
Right now I am set on the new line of Intel CPUs. The second generation of the core series is pretty awesome. They put up some pretty good numbers and I'm pretty impressed with out well they stand out among the crowd. As of now I am looking to get the Core i-7 2600K.
On the memory side I believe that 1600 will be the sweet spot. I am still undecided on what brand I will get. A-Data has proven to be very reliable and just as good as Kingston and Corsair. Crucial is still my favorite brand of memory. I am probably going to be picking up 16 gigs. Depending on if I get a different chip or Intel goes back to the triple channel RAM, will determine if I get less, but even then it will be 12 gigs.
As far as hard drives go, this will be a bit tricky. I want to get SSD drives, but they are still a little too expensive for me to drop the money on. Intel's new technology built into their latest boards is very interesting. It uses the SSD to cache commonly used files to speed up the HDD that is attached. Think of it as a RAID between mechanical HDD and SSD. I will probably get a WD black edition drive if I go this route. I believe I can offset the speed loss of Raptor by using this method. However, if in the next 6 to 7 months the price of SSD drives goes WAY down or I happen into a large sum of money, then I could totally see myself picking up a bunch of those.
As I just mentioned there is a new Intel chipset out for boards. It offers a couple new features. I can't wait to get one. MSI and Gigabyte are the brands I like to stick to, but I've had a couple of Asus boards in my last two PCs (which I've had way tooooo long). The P5N-E sucked. I hated that board beyond belief, but didn't want to go mucking about in my case or have to spend a day reinstalling my OS and games. Free time is at a premium and back then I was a very avid WoW player.
The video card debate is really going to be whether or not something has come out or is on the brink of releasing. I wouldn't mind grabbing another 6870 and running a Crossfire config. It really depends on what the price of a new high end card will be. The 6990 is still 800ish dollars. I have no idea what may come out or how prices will rise or fall by the time I decide to upgrade.
Yeah, I know I am planning in advance, but I want to know what to get. I want to be able to cherry pick the things I am putting in my PC. I plan to spend enough money that my wife will be upset if I don't just get everything I want. While I don't plan on spending 4 grand, I do plan to spend plenty of cash and get nice components, just in case I have another half decade before I get to upgrade again.
