Lookin for advice on Low Profile Cards

[Toxichzrd]

So my main PC is down till i can replace the motherboard. I'm currently using my old PC

Core 2 duo 2.89 Ghz
4 Gb DDR2
500 Gb Sata HD
8400 GS (SAD I KNOW)

my problem has become that since i'm giving this PC to my lil sister when i fix my main i want to put a good graphics card into it. I build this PC in an old Dell Low profile Optiplex case (this is not a dell i just used the case). This then becomes the problem the card i put in here must be a low profile card. I'm looking at (on Tiger):

EVGA SuperClocked 01G-P3-1435-LR GeForce GT 430 (Fermi) 1GB 128-bit DDR3

but when i looked up bench marks on it for BF:BC2 heres what it showed:

1024x768 DX10 4xAA

430 GT averaged 30.9 FPS
9800 GT averaged 55.7 FPS

now i know the 9800 is right cause thats around what i was getting with mine now i bought the 9800 2 years ago so its not exactly a new card but will the fact the 430 is low pro going to make that big of a difference??

my other question then becomes is there a better Low Pro option? I'm not worried about the price so much because its coming from tax return lol. but if i'm going to buy a low pro card i want it to be the best i can get.

Now i'm normally an Nvidia guy but i don't have any problems going ATI for this pc IF its a obviously better card.

any help on the matter would be greatly appreciated

The issue with the 430 is not that fact that it's a low profile but because it's not a very speedy card. Look at the charts here: http://www.tomshardware.com/reviews/gaming-graphics-card-radeon-hd-6870-geforce-gtx-570,2834-7.html, the GT 430 is 4-5-6 steps bellow a 9800.

You need to check on the power supply also, if you are using a small case, I'm thinking you won't have much of a power supply to run a powerful card. And you won't find many 9800 class cards in low profile, the card size just won't allow it.
