Thanks guys- blimey I am even more confused as to which one will fit and which to go for now!
Love the site JC Wolf and I am STILL playing u boat 1.2, and looking forward to the update!

I shall need to spend many hours trying to decide which card to go for, but wont need it until I go back to the other PC in France late in April, so have time to work it out.

Meantime, my nvidea GS 7900 is running the game beautifully here....!

Cheers :sunny:

The PSU power is very important - my computer had a 280W PSU so when I upgraded my graphics card I had to upgrade my PSU as well.

Most cards have a recommended minimum wattage - most of the new nVidias need 400W+ and I assume that the ATIs are similar.

By power supply I mean the PSU. I have a Chieftec560W. If you want to know whether a new video card will fit, check your motherboard. Please give more details about your PC . For example:
CPU: Brand(Amd or Intel), model( Core2duo, Phenom, Athlon, Pentium Dual Core) , frequency(2.2GHz). This is important because you need to find a balance between cpu and videocard. A very slow cpu and a powerful video card it is not a good ideea as well as a powerful cpu and a very slow videocard.
MB: The way a post it earlier ( Gigabyte Ep43-ds3l). It is important in order to know what kind of slot you have for the videocard.
Ram: Type( ddr2 or ddr3, frequency) It always helps to have more Ram. 2gb it is minimal these days, 4gb it is great and 8gb it is fantastic.
PSU: like Antec, Corsair, Zalman or other brand and the power, like 500w or more, or less. The PSU is very important because it provides power to the components in your PC and all the modern videocard usually need another connector for power besides what they receive from the slot. Especially for a video card the most important thing is the +12volts rail or rails depending on the PSU and how many amps they have on that rail.
CASE: Your PC case is important because some of the big videocard of today are, well..., big and they don't fit in smaller cases.
If you are not sure what to do go to a computer store near you and ask for proper advice. An also if you have a friend who knows computers go with him. It is what I would do if I was in your place. However be careful because from my experience they will always try to persuade you to fool you especially when they smell that you don't know much about PC's.
PS:
Regarding the 250GTS please remember that this card is just a 9800gtx+ renamed GTS 250.

Thanks- and here is my spec copied from dxdiag with the only change now that RAM is 3MB not 2.5 as on this list.

I appreciate your assistance on this matter, and I will have to check with a local store as the machine is in France currently and I am in England!

:up:

I looked over you data but I still can't find info about video card. Since it is a Ati do the following:
Go to Catalyst Control Center and look for the info like I posted in the screen shot:

If it is a PCI express then you need one such card, and by looking at your Pc, I personally would not buy something more than a Ati 3850 ar something similar from Nvidia like the 9000 series. However it it is a AGP card the you choices are more limited.

Thanks and I will have to keep that on record for when I go again- I can see the word PCI in amongst the data above, so maybe it is a PCI BUS ? :up:

Put a screen capture here to be sure.

Yer showing your age. ;)

Me too. I remember when Doom 1 was bleeding edge and 16 megs of RAM was smokin' and cost $600!

I can remember having a spectrum with a submarine game whose name escapes me, and droning across an empty blue patch for days without seeing the one enemy ship in the game!
That was the grass roots of my love of SH3 though I am sure! :up:

If it's the same game i had on the Amstrad 6128 then that would be Silent Service!!

great game for its time!!

Rick

Yes thats right- it was the original Silent Service and a cracking game for this time!

How things have changed is amazing! :salute:
