I was really more interested in a general opinion of brands than any specific model. I was wanting to know how brands like Dell, HP, and Gateway stack up when compared to each other. I don't plan to build my own computer. I use the computer for internet mainly, but this includes downloading large x-ray studies from the hospital for viewing at home. For things like CT scans, these are very big files, and I have to scroll back and to between hundreds of large x ray images. I also use it for more casual use of the internet, as well as playing some games. It needs to be fast, have a big hard drive, lot of ram, and good video memory/card.
How much are you looking to spend? Some of the companies do better with their top or bottom end...
I tend to do a 1-10 rating system for deciding what machine to shop for. 10 is hardcore computing needs, 1 is grandma and her email/browsing off of dial up.
General Internet use is rated at a 1 (Buy the cheapest machine you can).
'Large X-ray studies' I'm not familiar with, but at a guess I'd rate it a 3, with a caveat of buying the biggest, highest quality monitor you can afford, and a compatible video card. Otherwise, I'd give it a 3-5, depending on just how screwed up the software for handling those images are.
'playing some games' - Would these be 'immersive' games like Bioshock, or 'casual' games like tetris? Tetris gets a 2, Bioshock an 8.
For you, I'd shop around for a 'mid-range' machine, probably starting around $800, but upgraded with a better monitor.
For example, I hit dell up for their 'small business'(often better deals than the home site) - No monitor, 3GB RAM, 2.33Ghz Quad Core2, $643.
Unless you want the extra expense of getting a 64Bit operating system, it's not worth the $70 to get another GB.
Hard Drive, Dell wants $280 to put a 1TB drive instead of the default 250GB. Personally, I'd just hit newegg up for a second HD if it turns out you need the space - they're offering a WD 2TB(!) for $300, but I'd probably just go for the Seagate 1.5TB for $130.
$360 for a 24" LCD monitor, newegg sells them for as low as $270, but you can get a Samsung for $300. Only reason I'd consider buying it from Dell would be so the monitor tags along for any warranties.
$300 for a NVidia Geforce 9800GT isn't worth it when you can buy a EVGA 512GB GT for $130, assuming the default 256MB ATI card doesn't do it for you.
Hmmm...
Case&Power Supply, $200 est (I like LianLi cases and Seasonic power supplies, those won't be under $200)
HD, $130 Seagate 1.5TB
CPU/Motherboard:
$270RAM: 4GB $50(plenty to chose from)
Video:
$130Vista Home Premium: $100 - Can go 64 if you want.
Etc: $70(mouse,keyboard, DVD Burner, etc...)
I'd build a machine for $950, cheaper than a 'upgraded' dell at $1,223, but I can't compete with their cheap end.
If you're going to be a 'power' user, building your own still makes sense, but for basic machines, I'd buy from a company. Then get a good big monitor, varying from $300 for a 24"(1920x1200) to around a thouand for a 30"(2560x1600)
For getting the best deal, I'd get an idea of what I want, then keep an eye on the various stores, and wait a bit. Something will pop up.
