I decided on getting a PS3, now I have a few questions...

[Parasitic]

I bought UT3 today since it was only $17 used at Gamestop. There's hardly any online matches to pick from, which was sorta dissapointing. I didn't actually plan on playing it online alot, but I was using it mainly as an example, wondering if an old game such as that would still be somewhat populated. I guess it shouldn't be surprised since it's a year old....and they had the guts to take out the Assault game type =/ Does anyone know if Soul Calibur 4 is at least active online? I downloaded the demo and it's a tad bit fun.

Anyways.....I hear good comments about Uncharted all the time, so I'm sorta tempted to get it. The thing is I can't spend too much money on games at the moment so I'm looking for good quality games with high replayability (Of course LBP is on my list). How long does Uncharted take to finish? It's been over 3 years since I've been into console gaming, and this time around I'm sorta avoiding single-player games that are quick to finish.

So far, I have 2 minor issues with my PS3:

1: Everytime my IP changes, I get disconnected from PSN. I have to reconnect the ethernet cable back into my PC, then turn it on and get the new IP info then put it in the PS3's network settings. Is there something I can do to make my IP not change at all? It seems to happen randomly - I think the longest I've went without getting disconnected was 5-6 hours. Not a big prob, but can be a little annoying sometimes.

2: My sound sucks really bad. Before I got my PS3, my TV was pretty much unused so I'm pretty behind on times these days.....what would solve the problem better: a new TV or some good speakers? I'm using an old box TV from '04 - the image quality is pretty bad.

Thanks for all the replies so far.
