Gaming My (fairly outdated) build

[YayMii]

So I just updated my really old PC. I'm planning to buy a good PC next year, but I'm wondering if you guys think this is good enough for now.

CPU=Athlon 64 2.2Ghz (performance rated as a Pentium 4 3.2Ghz), Newcastle core, Socket 754. (going to overclock it)
Cooler/heatsink=Zalman CNPS10x Performa heatsink with fans from a Corsair H70 liquid-cooler (the heatsink is overkill, the fans are 58CFM hand-me-downs from my bro who got 110CFM replacements)
RAM=2GB DDR400 (1x1GB+2x512MB. clocked at DDR333, only because Socket 754 can only handle PC3200 speeds with 2 sticks. All are Kingston Value sticks)
GPU=Sapphire Radeon 4650 1GB GDDR2 AGP (Heavily bottlenecked by CPU, but can't really do much about it)
Audio=Creative SoundBlaster Live Value (unsupported by Vista/7, but I get along fine with modded drivers)
Hard Drive=Maxtor 6Y120M0 120GB 7200RPM (old drive, updating to a 1TB Seagate 7200.12 once I find a jumper to limit the bandwidth)
Mobo=Asus K8N (Socket 754, DDR1, doesn't support SATA2)

I upgraded it in hopes of playing new games, and it currently plays UT2k4 at 75-120 FPS maxed out. Do you think this is good enough for gaming?

ut2k4 is no benchmark

even my laptops radeon 4100 can play it maxed out on 1366x768 no problem

I only used UT2k4 because that was a game from when this PC was originally purchased (because my dumb geforce 5700LE couldn't play it at max)
