The Antec power supply I have right now has enough power for my system and is stable enough.
yes your psu can handle you system np.
but if you want a good video card, u have to change your psu.
back to your video card question.
x1950 pro for $200,this is a very good card for that price. if you want better, go for x1950xt ($270) or xtx($400).
or x1950pro CF for $400.
all those card i has list, you have to get new psu for it.
if you OCing those card.
pro need about 30A on 12v, XT about 35A.
i think your PSu right now have about 20-25a Only.
If you think no need to change psu? go for it! lol

go for those OCZ gamextreme 600W PSUs, they are cheap for the performance and are very good from what I hear. or you can always get a 550W antec truepower II(make sure it has the "II")

and, to all those who say the 3700 @ 2.9 Ghz bottleneckes the high end cards like the 7800, 7900 and the x19 series cards, what would NOT bottleneck? a x2 CPU? (x2 4600?)

A good ati card to get that draws of the pci e slot would be a Sapphire x1600Pro OC'd edition. It's factory overclocked to x1600xt speeds and has gddr3, I think it will do quake 4 just fine, but to get the most out of it crossfire would be needed. I myself sold two of those x1600's for one x1950pro which is actually faster then both of them. So if you can afford a new PSU get the x1950Pro, if not get the Sapphire x1600Pro OC'd edition from newegg for about $90.

If the most intensive game that you play is Quake 4 then you certainly don't need a x1900. A x850xt or 7600GT will run Quake at just below max settings at 1280x1024 resolution. If your budget is really constrained then I would get the 7300GT with DDR3 memory as they are very good overclockers, cheap, and draw very little power if you can find one that is.

Best price I found on a 7600GT $120 with a $20 mail in rebate.

Does this power supply have enough amps per rail for a better video card?

Look at one review:
Quote:
Set up nice, quailty cables, nice fans, worked wonderful for just about a month. Installed in new system, will all new parts... Asus M2N-SLI & AMD X2 4200+ & Asus GeForce 7600GS GDDDR2 & G.Skill 1GB PC2-6400 - - 430W should be plenty to run this system. Had 2 Seagate HD's as well.
If that PSU can keep that rig going, it's gonna be enough for yours, too. However it's not much of an improvement over your existing PSU...

Aside from that, your 300W antec should be able to power a 7300GT or a 7600GS without a glitch, but I don't know if your CPU OC is going to be as stable as you have it right now.
My advice if you want an ATI card would be the x1650pro which is better than the 7600GS in most games, but consumes less thanks to the 80nm process.

get one with 35A+. More AMPs = more room for later.

Yeah, I'd advise nearer to 40 Amps really.

A 7600GT is a great card. uses around 80-100W of power if I'm not mistaken. Brilliant card and won't suck your wallet dry either.

No pun intended
