PSU FOR GPU

First of all, hi every1. What i want to ask you, or someone that knows, is if i'll replace my graphics card with a gtx 460 se will i need a better PSU than the one i already have? My pc is a more than 3 years old and i dont really have the money for a new one, but i do have something saved for an upgrade. My PC specs are:
MB Gigabyte P35-DS3 rev 1.0
Proc Core 2 Duo E6750
GPU nVidia 8600 gts (but this doesnt really matter since i intend to change it)
one s-ata 250 gb hdd
2x1GB ocz 800 mhz
and the most important - a antec 430 earthwatt PSU (i got it with the antec NSK 6580 case)

Like i said before, i plan to buy a new video card...probably the one i already mentioned or a hd 5830 (cuz they almost have the same price), plus a new monitor (i would wish to buy a dell u2311 but its not currently available so ill have to wait or look for something else of almost the same quality and price) and 2 more gb of ram dual channel 800 mhz - thats all for now...

SO..Is this to much for my Antec EA 430 PSU? (I know that the recommended PSU must be of at least 450 watt but o dont know if that refers at the junk PSU or at the better ones).

I await your answers and thx for the help.

P.S. I forgot to mention that i wont buy a new proc or a hdd or go SLI.

DONT get a 5830, it is useless especially compared to gtx460. an alternative would be a HD 6850. Your psu will be fine for those gfx cards. forget sli with that psu though.

^You forgot "SE", in which the 5830 is actually a mild upgrade in comparison. However the 6850 is a much better card than either of the above.

But to answer your PSU question, you'll be fine even with a 6870. I would worry about your OS, CPU and RAM though. especially if you have a 32bit OS, you'll have an pretty bad lack of RAM in programs with a 1GB card. Your CPU, if still at stock clocks, wouldn't be able to keep pace with either cards well.

i have windows 7 x32 but i can change that to x64 (i have genuine licence for both :p  )

What is your budget? I would get another 2gis of RAM before a GPU upgrade.

i mentioned this before ... i plan to buy a new video card...probably the one i already mentioned or a hd 5830 (cuz they almost have the same price), plus a new monitor (i would wish to buy a dell u2311 but its not currently available so ill have to wait or look for something else of almost the same quality and price) and 2 more gb of ram dual channel 800 mhz - thats all for now... ill buy them all in the same time...

If you overclock that CPU, the 6850 would be a great card.

the 6850 i think its too much for me :)  ... but thx for the advice

btw...i didnt ask about the model of the graphics card...should i get gtx 460 se 1gb or gtx 460 768mb(i'm also refering to my exact pc configuration)...and exactly from what vendor, i can chose from these 3: eVGA, Palit, Gainward (asus, msi, gigabyte are over my buget)
I'll refer exactly to some models:

1GB

768MB

P.S. I mostly play MMORPG and RPG ... and the resolution of the new monitor i guess it will be 1920x1080.

if 1920x1080 is the resolution you want to play at with all or most details set to high, get a 6850 or 1gb gtx460 minimum (not the se version) if its really down to the SE or 768mb versions, the 768 is a little faster.

5830 would beat both 768MB 460 and SE, probably none of them will run on your PSU, also i don't recommend getting Palit and cards with central fans, the ones you listed have them, they are pretty noisy and unpractical, 6850 will run on your PSU, but with risk, will be bottlenecked by your CPU and probably will reduce it's life, usually DDR2 RAM is more expensive than DDR3, so i recommend selling your RAM and getting DDR3, it'd make your system more powerful for small cost

My MB doesnt support ddr3.

And here is a nice review of all the gtx 460 1gb graphic cards...
