Can Dell a XPS 420 handle 280 or 4870 1gb video card upgrade?

[AnMig]

Bought this system last year from hot deals xps420 hot deal

This was my first Pre-Built system, used to build my own. Its almost a year now (bought it 01/2008) and I need a video card update. My current 8800gt is struggling with Crysis 20fps 1440x900 high details. I expected this that is why I waited so long before I bought the game.

Quick Specs
Dell XPS 420 desktop
Intel Core 2 Q6600 Quad-Core (8MB L2 cache,2.4GHz,1066FSB)
* Genuine Windows Vista Home Premium with Digital Cable Support
* 3GB Dual Channel DDR2 SDRAM at 800MHz - 4 DIMMs
* 512MB Nvidia GeForce 8800 GT
* 500GB - 7200RPM, SATA 3.0Gb/s, 16MB Cache
* Blu-ray Disc Combo (DVD+/-RW + BD-ROM)
*Xi-FI Soundcard
*Winfast TV tuner
*Dell 24 flat panel Native resolution 1920X1200

I know it can handle a 260 core 216 without a PSU upgrade but wanted a faster card.
The Mobo is not SLI capable

Question 1
Can the dell 420watt PSU handle a 280 or a 4870 1gb

Question 2
Will the 280 or 4870 fit in this case

Question 3
Is the PSU proprietary or can I just grab 600watt PSU in newegg and be sure it will fit.

I know I am not the only one who got into this hot deal and was wondering how the other members upgraded there Video card and PSU.

Any help will be greatly appreciated.

Peace

Not what you asked, just a suggestion.

A 280 is not that much faster than a 260/216.. If you know, for a fact, that it will drop right in without any other mods then I would go for it

If you want a faster card then a GTX260 then you should probably not consider the 4870... it really is on the level of a GTX260. You'll want to look at the GTX280 or think multi GPU.

I *think* the 4870 is shorter then the GTX2x0 cards.

I can't answer for your computer in perticular, but I have a coworker that upgraded his graphics card and power supply in his Dell PC, it was standard ATX, not a proprietary unit.

I guess you have a point the 280 I figure is around 10 to 15% faster than a 260. May go withe 260 instead.

Thanks for the PSU info glad to hear that its not proprietary.

May wait till this Thursday and see how fast the new NVIDIA card is.

Thanks for quick responses
