Questions about buying from Dell

I'm not sure if this is where this thread goes, sorry if it isn't.

I'm considering building or buying a computer fairly soon. Dell has a great deal on a vostro 220. I have a few questions about it.
1. Is there any reason that I shouldn't order from Dell's business section? That's the only place that has this deal.
2. The graphics cards from dell are overpriced and underpowered. I would just go with integrated and then get a graphics card from newegg. Would the dell have a PCIe x16 slot? Would the power supply in there have a PCIe connector?
3. Is there software that can overclock an OEM machine? It would be a shame to get an OEM with such a good overclocking processor (e7400) and not use its potential.
Thanks for the help,

no please dont fall into the dell trap!! back in september i bought a xps 630i and paid $1800 for it and the parts that were in it were no where near worth that much. it came with a q9300, a 650 sli mobo, 3gb ram and sli 9800gt. well not worth the cash. the only parts worth anything was the 750w psu and 320gb hdd. the mobo didnt fully support yorkfeild cpu's so absolutely no oc;ing of cpu, it was just a mess. i ended up putting a evga 780i sli mobo in it and 4gb of ocz sli ram (got suckered into that) and dual evga gtx 260-216 and that is closer to being worth or possibly more than $1800.

just build your own, you could build one that would crush any dell for so much cheaper. i learned the hard way. i have just recently built a gaming pc with a E8400, 6gb ram, xfx radeon hd 4850, asus p5q pro mobo and a 630w rosewill psu which im getting a 850w next month because i plan on tri-firing 4850's with a 4850 and a 4850x2 so i need a little more juice to be safe. and if i bench my 2 pc's against each other (turning off SLI in the dell of course) my newer pc gets better results in the crysis benchmark. and thats all highest settings and 4xaa/16af on 19 inch lcd with 1400x900 res. save yourself money and a headache go homebuilt. i will NEVER buy another pc from a company again.

and also if you build you will know exactly what the pc has and can do. good luck

Dell are ok if they have a machine that will do what you want at a price you want to pay.
The main issue i have had with Dell in the past is that they use non standard parts which makes upgrading difficult or impossable.
Just check how many posts we get about what people can get that will actually fit in a dell.
So if you want a gaming machine forget it, build yourself one or find a good system builder through word of mouth/recomendations on forums etc.
If you want an office machine get a dell, if the price is right.

Thanks for the help, I'm going to build the system myself. Any help would be appreciated in this thread: http://www.tomshardware.com/forum/ [...] ood-system
