The Sparkle 9400 has a PCI-Express interface as far as I know.
The PCI slot will not work.
The Dell power supply probably need to be upgraded too.
What are you basing your reply on? The Sparkle 9400 comes in at least 2 versions, one of which is PCI, not PCI-E. Also, why would you say that the power supply needs to be upgraded, when the PCI version doesn't have a 5v connection. Please support your statements. THANKS for your prompt reply.
Do n`t see why it wo n`t work, the card draws a tiny amount of power and will display to that resoloution.
BUT.
Read the customer reviews on this page before making the decision.
Hi, sorry to be a bit late, I just found this thread. I'm using the slightly earlier Sparkle 8500GT PCI card in a dell dimension 2350. Works fine, though I don't have a monitor capable of the resolution you describe.
I have got a 400 watt PSU as my old dell PSU gave up a few years back.
