[Phalanx]

So a month or sometime around then ago...I got a more or less new pc, 2HDs in there, runs quite well, and a
Geforce 7300GS
Which isn't great, but I assumed would play most games...

Anyways, this is what it says in my system specs...
There's a p4 3GIG in there.
2x 1.99 gig of ram

That's all the info I could find, so I've got that, and the gf7300gs.
I also got a new motherboard...something about SLI or whatever...

Anyways, first a question.
I understand I can put an additional graphics card into the motherboard...is this true?

I have a friend who CLAIMS that if I were to do that, it would have to be exactly the same brand and model as the existing graphics cars, is THAT accurate?

Ok...another question - SHOULD this system be capable of playing F.E.A.R and games of that calibur.
See, I bought it last week...and ended up taking it back...it played but there was still some I dunno...like it skipped during play?
Yeah, I COULD have played it, but IMO this minor problem would've spoiled it for me.

Another thing I've noticed is that with other games, even with older games,
during FMVs and gameplay, sometimes a horizontal line goes up the screen?
It's not too much of a problem, but I'd prefer it if that DIDN'T happen...I mean it happens on silent hill3 (same prob with FEAR), it even happens on full throttle and Runaway.
Any ideas what the problem is here?
Is it a settings thing, or is this card particularly shithouse? I mean I've read there's some issues with it as it's set for 64 rather than 128 or some shit like that...but I'd think that since it was new-ish, it should perform a little better one way or another...

One more thing....if I DID go ahead and throw yet another graphics card in (same model, or higher) would that make a great deal of difference or not?

Anyways, here's hoping someone can help out...
