Am I being realistic?

Don't do it! Something like this is a better option http://www.tomshardware.com/reviews/build-a-pc-overcloc...

Building a computer can be much less expensive then buying a pre-built.And don't make the same mistake i did,that is a multimedia PC.If your a gamer you do not need a Multimedia PC,it just puts extra costs that you don't need to spend.

At that budget $140 theirs nothing you could buy that would give you any type of performance gain over the 9800gt.

Building your own computer is the best option in my opinion.
What type of computer do you have now?Plz list full system specs(RAM,mobo,PSU,etc.,etc.)

Actually just looked at the link rolli59 gave and it looks like a really good deal.460gtx would be a nice improvement over the 9800gt.But it doesn't have the full 1G which you might need running 2 monitors.

I'm not upgrading the computer I have right now. It is just a little guy...
It's a small case that my ex GF got me.. 9800GT is really the only thing worth salvaging.
I like the link you provided for me.. is there some sort of tool for sorting all of this information nicely?
Like...does newegg have some sort of computer builder utility or is it just the cart?

Just drop it in the cart, you can modify it at will until you buy.

Then they have great combos very powerful CPU! http://www.newegg.com/Product/ComboBundleDetails.aspx?I...
add your 9800GT (for upgrade later) and you have a gaming system

I don't care about HUGE FPS I just want to run a game smooth on one monitor, and watch video on the other. Do you think it will happen with my 9800? Thanks for all the posts! Keep the advice coming  

If you do not care about massive fps and willing to lower settings a little then the 9800GT will handle it OK.

I'm playing around with this system builder marathon link you posted.. making a post on this website was a great idea.. you have been a load of help already!

That link he provided is a fantastic deal.Adding another 9800gt for SLI would give you great FPS too.

I would buy that combo

I'm tweaking with it ATM. I think I would prefer another case...

I really like the idea of the built in power supply... a lot of the cases that I am looking at have complaints about theirs...

You could salvage some parts from your other computer.That is why i was asking what your full system specs were.You need at least a full Mid-Tower to accomadate the mobo.And SLI'ing 9800gt's is a good idea if you already own one.

I didn't take a W7 license into consideration...

If you are going for a cheap budget system, NewEgg is the way to go. They always have great deals going, and you almost ALWAYS get better value from getting the parts and doing it yourself, because you know exactly what you want, and the 9800 GT still has a value of around 90 bucks, so it would be good for what you are trying to do.

OOOH... I just remembered my MSDNAA login... YAY W7  

You an salvage the HardDrive and RAM.4G of RAM is a terrible thing to waste.Is it DDR or DDR2?Whats the speed?
Did you even want to salvage parts from it or use it as another PC altogether?

I'm thinking the Graphics Card is going to be the most expensive thing so go with a gtx460 or a 6850 and then work from their on what parts you can fit into the budget.
Although the combo he has lined up for you looks really good.SLI'ing 9800gt's aint a bad idea at all and should last you another year.Also the SandyBridge i5's are brand spanken new and their really good.But that also means prices are going to drop for AMD and Intel's older model chips.

I think a 6850 is what's going to happen with the GFX card... is this a good idea?

The HD6850 is an excellent choice.

You think it will offer improvement over my 9800 then?

http://www.newegg.com/Product/Product.aspx?Item=N82E168... Is my case/PSU choice.. Best ratings, seems like the power supply is actually worth something in it... anything I'm forgetting... like thermal paste, or extra cords?

You should look for the items with free shipping.Shipping really starts to weigh on the budget.

the power supply in that case is crap, dont bother with case/psu combos, the psu's are always crap and wont last more than a year and can potentially destroy everything else in your computer when they go.

Not always true, Antec pairs some of their cases with their Earthwatt power supplies, very good case/PSU combos there. It's just like 90% of case/PSU combos that are crap.

I would also agree,most of the time the PSU&Case bundles aren't of very good quality.

Were you going to save the RAM from your other build or buy new?

fair enough if you want to get picky 90%. I would even go 95%, Antec are pretty much the only hope when it comes to reliable case/psu combo's.
