Ok, I have several 410's at work that have been upgraded lately.... The psu that you have is 375w and its not considered reliable when you decide to upgrade the video card.
I would suggest that you upgrade the PSU if you are thinking of buying a 4890. With the stock specs of that pc, you will end up bottlenecking anything over a GTX260 as far as Nvidia goes and a 4870 (1GB) Ati.....
The RAM on the 410 maxes out at 667MHZ, meaning if you still have the stock RAM, you will be better off buying 2 sets of this before you upgrade the GPU :
Since your parents are most likely not to buy both the PSU and card at the same time, I would recommend going with a 4850 as opposed to the much more expensive 4890 for now and since you saved some cash try convincing them to get at least a 500w PSU.
Negative Sir, the 410 is just like all the other Dell's . When you buy one you can change (upgrade) any parts while you build it online or on the phone. Meaning if you went with a more powerfull GPU that would require a more powerfull PSU then they would ship the pc with a 450w or 550w depending on what GPU you purchased.
When I purchased a couple of 410's back in 07, the first one came with a 375w PSU and an ATi x300 video card, the second one came with another 375w and a 1600XT and the the third one came with a 450w and a 8800GTX.
My parents aren't buying this for me actually (dunno where you got that idea hahaha but whatever)
So... all I need to get is that new PSU and two sticks of 2 GB RAM and then the video card?
Excuse my ignorance but isn't that RAM you linked me OvrClrk still maxed at 667Mhz (and would thus still bottleneck the HD 4890)? That's what it looks like it said in the specs at least.
Also... it looks like the brand of HD 4890 I was going to go with (Sapphire) actually ships with a 6 pin and 8 pin. Is there a PSU with that config... or... even better one with 2 6s and one 8?
Dell told me my motherboard would not support that video card (because it didn't have a six pin connector). Were they just flat out wrong? Do I not need to worry about upgrading the motherboard at all in this? (I'm almost a complete hardware newb so bear with me please)
Also would you guys suggest I upgrade my processor? Would having the original processor severely limit the power of my GPU? What processor would you recommend?
Finally... I hear this card (the HD 4890) is really hot, do I need to worry about adding an extra fan or upgrading the heatsink or something?
Thanks a lot. Would love to get in the newegg order by the end of today .
Dell only offered the 410 with the 375 watt psu, the next gen XPS420 was when they started doing psu upgrades according to the card that was chosen at the time of purchase and that was a 425 watt unit.
Dell told me my motherboard would not support that video card (because it didn't have a six pin connector). Were they just flat out wrong? Do I do I need to worry about adding an extra fan or upgrading the heatsink or something?
Yes they were, the motherboard will support it, though it is only PCIE 1.0.
Upgrading the heatsink would take some modification.
An extra fan or 2 on the back grill will help with heat.
IMO converting a molex to a 6 pin connector is not the correct solution as far as the 4870. Of course anything under the 4870 should work fine, again this is my opinion and others might not agree.....
I agree with this, but most manufacturers do provide the molex to PCIE adapter, and it's probably better than Dell's method of using a PCIE "Y" splitter ( That's how they powered the 8800GTX off of the 375)
