PC upgrades advices to use 3 monitors

you can't hook up 3 monitors to a 9400GT but you can hook up 2 by DVD and VGA
just put the cables

If you want to change your VGA,then make sure that it's an ATi,because their cards can handle more than 2 monitors (not all of them). :)

He meant to say DVI not DVD.

Shekval, do some research on ATI Eyefinity and then decide on which card you want based on your budget.

Can i hook up 3 with nvidia with multiple dvi outputs like the pic below?

you can do that but 2 of the monitors would show the same, you can't do gaming on 3 monitors or drag stuff between 3, using that cable would be like watching a movie thats connected to two tv's, you can get the gtx460 if you want, its a little more than 200$ but its powerful and you can connect 3 monitors using 2xDVI and 1x hdmi

gtx460 or gtx460 sli ( difference, if there is ? prices if you know, thanks in advance )

The question isn't for me but I'll answer =P

SLI word means 2(or more) NVidia cards put into the MoBo (it should support SLI, and your power supply should be able to afford the power of two video cards) and connected by SLI bridge, they must be the same cards, let's say GTX 460 in this case.
CrossFire is the same idea, but for the ATI cards.

Regarding the difference, AFAIK (according to tests and benchamrks), it won't double the frames per second (the most important thing in gaming) displayed on monitor ( I'm talking, here, about one monitor. Google "three monitor difference sli" or something like this to find out if it's worth it).

And lastly, price will double for sure =P

umm, I have the 1 gb nvidia gts 250 and it has 1 slot for vga, 1 slot for dvi and 1 slot for hdmi... and its only 137$ on pc and parts(without vat)....

AMD (ati) cards with Eyefinity allow three monitors with expanded view.

Nvidia cards allow two monitors with expanded view.

Nvidia SLI cards allow three monitors with expanded view.

Nvidia GTX590 (dual gpu) allow three monitors with expanded view.

P.S.: Stay away from AMD

note,using a gtx460 with that processor will bottleneck, bottleneck means that a slower hardware in your pc prevents the faster one from being so fast, heres another way of explaining it, lets say the gtx 460 gives you 60fps in crysis 2, your processor will bottleneck your graphic card thus the game will run in 30 even thought your graphic card will do 60, although you shouldn't have problem running games across 2 monitors, its in newer games that will bottleneck, by the way, don't confuse gtx460 with gtx460SC, the sc one is slower, and do not get the 768mb version one, instead get the 1GB, to be honest id get a GTS450 or 550 with your rig
note the fps is just an example, doesn't mean your game will run 30 or 60fps like i said

EDIT: i just checked prices on pcandparts.com
considering there isn't much difference in prices between the gts450 and 460, the evga 460 seems the best option, i have it and i love it, its external exhaust so you don't have to worry about it heating up your case either, the 550 is N/A

price:
EVGA 01G-P3-1371-TR Geforce GTX460 1GB DDR5 Dual w/TV $215.00 PX-58
