Desktops forum: NVidia Graphics Card Upgrade Advice Sought!

Hiya!

First, thanks in advance for answers. I long ago lost a handle on the state of hardware and system building, and looking at what's out now vs. what I have is causing me massive headaches of garbled tech-speak.

Here's the situation: I just upgraded my Alienware to Win 7 64 bit, with a Z68XP-UD3 motherboard w/an Intel core i3-2100 CPU @ 3.10 GHz with 8GB of memory.

Since upgrading, things are MUCH more back to the game-crushing system it used to be, but as my system chugged along a bit in Borderlands 2 the other day, I realized I'm still using my old video cards: 2 GeFore GTX 260s in SLI mode.

I was hoping someone could give me some upgrade options. Here's the thing... I have no income, so I only have a few hundred dollars. I was looking on newegg and saw quite a few things in between $50 and $119, so I know there's something out there better than my 2 260s in SLI, that won't break my bank. I'm hoping there's even something that would be a solid upgrade that will allow me to buy TWO (again, for roughly $200 max) so I can SLI and maximize the power and length of time I can go before needing an upgrade again.

Right now, reading all the cards that are out and all the new techs and abbreviations that now tag along, I'm getting lost as to what even works on my system, let alone what's better and what I might be wasting money on. Hoping some of you who love upgrading systems can point me in a good direction!

(I'm good with one card options as well, as long as it's one card that's going to last me another 4-5 years with better-than-average settings. I don't have to have ULTRA settings in 2-3 years, but it'd be nice when I first upgrade.)

Oh- I prefer to stick to Nvidia cards, for the record.

Thanks again!
