Well I did some research finally regarding whether I can play Oblivion on my PC. My plans for getting the 7800gtx video cards are dashed since I only have an AGP interface. I don't plan on buying a new computer anytime soon. So here is my dilemma which I hope someone here can help me decide.
Option A: Buy a Geforce 6600... Still appears to be a decent card with 8 pixel pipes for about $120. I don't think I need to make any other changes to my computer with this option.
Option B: Buy a Geforce 6800GT or Ultra for about $280-$300. Seems to be much more powerful with 16 pipes and higher clock speeds. My concern here though is I checked with Dell and my comp only has a 250W power supply and the 6800 recommends at least a 350W.
I am not too worried about the price difference of the cards, but I dont want to sink another $100 into a better power supply too. Will the 6800 even run in a 250W environment? and if so, how much of a performance hit will there be?
I would be grateful for any help here...
I had that EXACT same dilemma once upon a time. My power supply in me dell went bad once so I called to get another one and they said the only kinds they had were the 250W variety, which wouldn't run what I was upgrading to. So I bought a new Motherboard, Power Supply, Memroy, Processor, and case.
Anyway, the guys at compUSA (never go there, they are terrible) said that only a dell Power supply will fit in a dell case. I'm not so sure about that. I once took my dell PS and put it into a Compaq case and it fit fine.
So... with all that said, I would choose option 'B' because the 6800 Ultra has 16 pipelines (as you've already mentioned) and it has support for Pixel Shader 3.0. My Radeon x800 pro has 12 pipelines and only supports PS2.0. Buy yourself a new power supply too because it will probably benefit you in the long run if you ever want to upgrade more. Make sure it will fit in your dell case though, I'm not 100% sure it will but I think it
should fit. Running the card on anythgin less could potentially compromise your entire system, I added a DVD Burner to my dell and that's what did my PS in.
Rosewill makes good inexpensive power supplies. All of
these power supplies are under $35 USD.
