I happened to read the PSU sticker on a Lenovo desktop at work... 223 watts with 12.0 amps on the 12 volt rail. AWESOME!

please post details on Amperes for 12V rail... so many PSU even with 500watt labels that have very little amps

Keep this in mind in terms of Nvidia vs ATI. Old Nvidia cards can be used later on as PhysX cards. ATI cards can't. I know... many people say that PhysX will die soon, but there have been lots of major companies licencing it from Nvidia. It might not be dead soon. Wouldn't it be cool in a year or so from now when you upgrade again to have a use for that old card?

Look at the sticker on the side of the power supply, tell us how many +12v rails there are and how many amps on each. For instance mine has 2 +12v rails and they both have 18a for a total of 36a.
You cant really go by wattage because lots of companies exaggerate the wattage. Amps are whats important.

I had 1 GTX+ and my power meter was showing 300watts gaming.

With the SLI its about 425-475 on full gaming.

why not buying a GTX+ ? about the same price for better price ?

Zipzoomfly has a 9800 GTX+ for 160 bucks... then you can mail in the 20 dollar rebate. That 160 includes shippping!!!

If you have a PSU that only has something like 15A on the 12v rail then it could be a problem. If you have 20A or more you should be fine. If you have something like 17/18A then it depends on the quality of the PSU since many cheaper ones can't actually sustain anywhere close to that and thus may not be enough.

9800gtx is a little faster (see benchmark totals), and i always prefer nvidia drivers over ati. plus, if you play any games that use physx you will see a performance boost with the nvidia (ati cant use physx).

9800GTX+ would be better than 9800GTX as it is more faster and less hotter.
For 4850, it comes with a single power connector. Minimum 450W recommended.

No, it's not. 4850 is a bit faster than 9800GTX

8800 GTS 512 = 9600GT = 4830 < 9800GT < 9800GTX < 9800GTX+ = 4850 < GTX260 < GTX260+ = 4870 < GTX 280

Well the 9800GTX is just a relabeled 8800GTS 512MB, the HD4830 is about the same as a 9800GT and the GTX260 216 is faster than a HD4870.

Agrees the 4830 and the 9800gt trade blows the 260 core 216 is a skinny gtx280 and is a lil faster then 4870 1gig but its really close benchmarks is required to measure the difference unless someone know the difference between 60 and 61 frames

From Toms chart ...

Sum of FPS Benchmarks 1680x1050 AA
NVIDIA Geforce 9800 GTX+ 512 MB = 512.10 fps
ATI Radeon HD 4850 512 MB = 441.70 fps

Sum of FPS Benchmarks 1680x1050 noAA
NVIDIA Geforce 9800 GTX+ 512 MB = 570.40 fps
ATI Radeon HD 4850 512 MB = 536.50 fps

We could tell that the GTX+ is a lil better ...

From Guru3d....

CoD4 1600x1200
# 4x Anti Aliasing
# 16x anisotropic filtering

4850 - 56
gtx+ - 54

Crysis - Single Player v1.2 1600x1200
* 0x Anti Aliasing
* 16x anisotropic filtering

4850 - 43
gtx+ - 47

Seems like both cards trade blows equally....sometimes the 4850 is slightly better...other times the gtx+ is slightly better.

As already mentioned, the 4830 should be boosted up in that, as well as the GTS-512 is higher than the 9600GT, there are time when they'll come close to equal, but once they get stressed the GTS-512 starts pulling away overall the GTS-512 is better than the GF9600GT.

Yup your right, but i love my GTX+ ;)


Both card are good. Price is good, perf are good. GTX+ can now be found for under 150$. same thing for 4850. Dont go for the GTX+ 1go ... pricy for no reason.

20amp on a rail is enough. just une one rail for you CD-DVD-everything, and the other one ALONE with the card.
