More Computer upgrading funFollow

So, I bought a new 512MB stick of RAM after having played a couple of days with only 512 total on my board. I have 3 DIMM slots and one of them decided to die on me(YAY?). Now I am running on 784 MB and it's running much better, but I'm thinking it's only a matter of time now before one of the other slots die on me. Great, so forgoing the option to pay off some bills with some extra cash I've got saved up I've decided to spend my hard earned cash on a new TV (because my TV is also about to die on me) or upgrade my computer. I just recently replaced my Klipsch 4.1 speaker system on which the control box failed, I was getting sound out of either the right channels or the left channels, but not both at the same time. I picked up a nice Onkyo HTS for around $300. So it seems I am traveling down the path of aged electronics, slowly but surely 1 by 1 various components of my netowrk of entertainment goodness are leaving me to travel the road to defunct. About a year ago my moniter took a dump on me and the brightness level dropped drastically, I upgraded to a Sony LCD, Which I love, however it does not have a DVI interface. So, after all this rambling here is my dilema. New TV or new PC parts? If I upgrade my PC I'm looking to go with at least a 3ghz prescott chipset on a new 925xe chipset (gotta have a 1066 FSB). Doing so means I need new RAM so I'll need to pick up at least 1gig of PC3200 if not PC4000, also with the new mobo I'll need a new vid card since all of the new boards coming out have done away with AGP in favor of PCIex 16x. If I get a new TV I'll pick up a nice 26-32 inch HD screen with a DVI input which I can plug directly to my current vid card. and play EQ2 on in 32" greatness...even though I could also just lug the PC to the living room and play it on the big screen. Anyway. What I'm looking for are suggestions on motherboard/vid card combos I also know that people have a preference on the brand of RAM they use, the new one I see floating around the hardcore gamers is OCZ and I hear about Corsair a lot too. I'd like to spend less than $800 on RAM, CPU, MOBO, and GPU. The motherboard needs to support IDE RAID, I don't want to upgrade to SATA yet, I've got a good sized RAID alrwady on IDE 133. I'll be porting over the rest from my current set-up which is:

1.6A P4
786MB PC2100 RAM
BFG Asylum Geforce FX 5600 128MB
Plextor DVD +/- R/RW
Soundblaster LIVE
Main HD: 120 gig Maxtor 7200RPM
Secondary: 160 gig RAID(2 80 gig Maxtor 7200's)

If you've taken enough time to read all of this let me know what you think a good MOBO/RAM/Vid card combo would be.....and sorry for the long email, I'm bored at work and the phone's not ringing.
