    unfortunately im not at that level with pc hardware - I'd be better with software and os

    It's a dell xps 420 x38 with the larger of 2 psus for no more than 8800gtx

    see I'm only a mere mortal!

    Ahhh, gotcha. :(

    Dell proprietary crap really hinders one's ability to keep up with the times. But hey, that just makes you buy another one of their systems. Smart from a sales standpoint I suppose.

    of course I agree with you to a point, but I must say x38 & e8500 are a beautiful matchup in games (when quad core game programming becomes the norm, then obviously I'm screwed) with pcie 2 when/if that becomes important.

    I just need to keep an eye on the 8800gtx wattage threshold as the gpu gens move on, but the reduction in nm obviously helps a bunch re: fps/watts

    Ahh, but for what you pay for one of those Dell rigs, I could build the exact same thing and have enough money left over to upgrade it several times. But hey, to each their own. I still think that you'd be fine with a 4870.

    Don't get me wrong - I'd absolutely love to be able to build a pc from scratch - I understand all the principles and I'm sure I could learn all the technicalities, hey I might just do it!

    But I'd put a lot of currency in your advice re: 4870 -

    What do you make of the difference here:

    What are the exact specs on your PSU? That would help a lot.

    I'll be with the system again on Monday - I'll read the details off the side then
    but it handles the 8800gtx very comfortably, which it was designed for

    I'm just wondering is there an explanation for the difference in those 2 links above, since everyone seems to agree 4870 (and 260) consume way less power than 8800gtx

    I would think that the differences would be trivial. I came across these-

    I think you'd be just fine with a 4870.

    From that I guess there's no way my PSU would handle two 4870x2's in crossfireX. Could probably get away with crossfiring a 4870x2 with a 4870 though...what do you reckon?

    Agreed. The 4870 would be my recommendation aswell.

    Heya Jimmy545,
    Swapping power supplies in a dell is really pretty easy. I'm not sure if it's like an XPS 410's innards but I did a PSU swap on my brothers dell and was a 15 minute job. Dell does not use proprietary psu's in their mid towers to my knowledge. Biggest pain was cable management, but that's the norm. Your 420 should have a motherboard diagram in the manual so you can figure out where to plug everything in. Time to stop being a mere mortal ;)
    What is the PSU rated at the 12v rail in that thing?

    Oops, I didn't see that you said two 4870x2's in Crossfire for a total of four. Nope, I wouldn't even try it. Maybe with a 1200W PSU... :)

    well spotted, but here's 3 that conflict with those and suggest 4870 is closer to 9800gtx than to 8800gtx for load watts..

    I'm leaning back to 4870! :banana:
    will wait for more reviews


    @ blownapart
    wow the thought of being able to upgrade the psu is definitely appealing - I had heard to just not consider it. I need to get me some expertise

    Quite frankly, I trust the two that I cited quite a bit. You'll be just fine using a 4870. And if you can wield a screwdriver, you can replace a power supply. :)

    Hmm, strange those power levels are different than I've seen elsewhere. Maybe those include the new Powerplay activated in the drivers?

    Well I understand that besides the 8.6 hotfix, which you could more accurately call 8.7 alpha, there's now also an 8.7 beta, and I guess when 4870 officially launches, ati will have 8.7 whql for download in the normal way, which definitely should have powerplay working.. :)

    Hey jimmy545...I'm sort of in the same boat as you and wanting to upgrade to the GTX260 or mayby the HD4870. Power consumption is also a very important consideration for me also. At present they both seem to be neck and neck under load with the difference negligable. I have decided to wait and see if Nvidia comes out with a 55nm version of the GTX260, which I suspect they will soon. If it happens the price should be better along with its power requirements. As it stands you have a very good card so I see no reason for you to be in a hurry. Another consideration that I have not heard discussed is that (from what I have seen so far) the HD4870 only comes with a 2 year warranty whereas my current XFX card comes with a double lifetime warranty which means I can sell my card and the warranty carries over to the new owner. Just my two bits worth...

    you shouldn't care so much of how much watts or w.e it uses for gpu.

    you should compare of performance because that is what it matters really
    and so far, go for ati 4870, or even better wait for 4870X2 which outperformes a single gtx280 and cost alot less.
