Ok, This is the laptop I have... (for the most part)
Mine, is the 'slightly' older version, only diffrence is mine has 3gb memory, and it has 4gb, mine didnt come with SP1, and it does.
I'm not gonna do a sexy picture of the performance...
Gaming Graphics: 5.8
Overall quite the impressive score for a lap-top. And really not that bad of a price, I got mine on sale for 1250$
Quite a bit more than yours in cost, but it's a lap-top, pre-built, pre-installed, and worked out of the box flawless and as the numbers show, quite a bit faster.
Really that 'full crysis capability' is quite a load of BS, as my desktop, can NOT run crysis at FULL(and it's about 30% faster than my laptop, which is double the speed of yours). The only person I know, (in person) who has a computer that can do that, is my brother, and he has a 4000$ computer. (it's psycho, over-the-top, and I am by no means saying you couldnt build a system for less to do what his can... well actually you couldnt, but you wouldnt need to either)
EDIT: I just want to say, I just noticed your, "Spend 1,000-1,500 on an almost good enough computer." I spent 1.250 on my laptop, and it's WAAY faster than your 'good enough' computer. Just dont buy an alienware, or a high performance DELL. Look up ASUS, they have some custom build laptops/computers, that will just blow your mind, for really decent prices.
The link I provide, is the "ONLY" gameing notebook for under 2000$ that is NEAR as fast as it is. And it's WAY under 2000. It goes cheap on processor, memory, screen. Not the Video card. A true gem.
Also, do yourself a favor, and add 300$ for windows, as you did not include that. So your 'so-so' custom made computer after monitor, has now cost around 1050$, while my laptop only ran me 1250, yet it's faster. Building custom computers are really fun, but it's not that cheap, unless you go 2nd from best. As if you go 'mid tier' you really wont save that much money.
If you build one, go cheap on the CPU, go all out on the memory, and buy the 2nd fastest video card on the market, after *everything* including HDD, you are looking at about 1300-1500$ and that is a seriously moster of a computer. I really dont reccomend you to build your own computer, uness you know what your doing, as when you build your own computer when something breaks, even in the first 20 days. (very common) you have no way of diagnosing what happend, and you end up either not fixing it, or spending WAAY too much to fix it. I just re-built my desktop. (changed the HDD's in it around a little for a fresh install, and minor upgrade with DVD Drive, and add a HDD) One of my SATA wires came out of the end about 1mm, and if I didnt know exactly "where" the problem was, I would have never found that, got a new HDD, then it wouldnt have worked, then probibally a new motherboard thinking my SATA bus was gone, and then I would probibally end up using a new wire from the new one, and when that worked, I just spent about 250$ on a problem that could have been done for under 5$.
I've been building computers for over 10 years, I'm not that old, and I'm always tinkering in, on, or something with one. I honestly cant reccomend the 'average' person to build a computer as it is a very... challenging process.
And dont think you could check the HDD on your 'old' computer, as it would likely not have SATA, and only have IDE, and there's alot of stuff like that in new computers, that is 100% not compatable with old computers. Also if you are buying a computer, you have to make sure you order the right parts, as if you order a SATA drive, and your motherboard does not support SATA, you have a HDD that you can sit and look at, but not use.
EDIT2: Also, something is MAJOR wrong with your rig, you should be pushing at *MINIMUM* a 5 in graphics. Your card is the same as mine. (clock, and pipes) You should be next to identical to what my laptop pushes on graphics. I'm curious do you know what multiplier your PCI-E runs at?
EDIT3: I play Age of Conan at max. ;)
EDIT4:I didnt see the fact your vista score was NOT with that hardware setup. However in that setup be-weary about the on-board video card, as I have encountered some major problems with those, and trying to put on the big ones.
