ATI Radeon HD 2400 XT vs (2) eVGA Geforce 7800 GT

[The1nk]

Hey all.
I'm writing here because.. well.. It's a video card forum, and I have a video card question!

My current PC is a Gateway <something or other> and has an AMD Phenom Quad Core 2.2ghz Processor, 2x 500gb SATA hard drives, and currently has an ATI Radeon HD 2400 XT 256mb video card. I'm having a very difficult time finding some full specs on that card. My colleague is selling 2x eVGA(brand) GeForce 7800 GTs 256 mb cards, with a SLI linking thingie for $100.

What I'm trying to figure out is whether or not its worth it to buy those two new cards, and replace me existing card with those two ? My common sense and basic computer background is telling me - "Two is better than one!" but if they're each much weaker than my current setup, I can't imagine much would be gained from the transaction.

Any thoughts/comments would be awesome, as I'm completely lost on this subject -- Ever since these PCI-e cards came out, I've no idea how to compare them.

Thanks!

don't bother SLIing them because your motherboard probably doesn't support it. Even if it did i wouldn't recommend SLIing 2 old cards.

Get a 4850 $120 after MIR

Blow those cards out of the water even in SLI, not to mention all the extra goodies you get getting a up to date card IE shaders HD DX10 etc etc

oh and it would be a Huge upgrade from a 2400.

That's actually not that bad of a price. and it'd be a huge upgrade? O.o
[How bad is my current video card? ] I don't exactly have the need to upgrade, but I can't run Fallout 3 on high, so, there's the need for me.

Thanks for the input!
