The gt240 is about as fast as a 9600GT. A 9800GT would be about 30% faster.
All of those are DX10 cards, I would not recommend any of them for Civ5, where those cards have tendency to cause trouble
The only logical choice in that pricerange is the HD5670 at the moment, but the aquivalent nVidia cards will be available in two weeks.
If you buy a GT240, get one with 512MB GDDR5 VRAM. 1024MB will at best be as fast, and as a worst case significantly slower (depending on the used RAM type).
Thanks guys. As my gaming desktop runs XP, I'm not too concerned by DX 10 or 11, but I understand your point about 10 to be avoided.I second the recommendation on the HD5670. Mine works splendidly on the CIV5 demo.
The 512 MB (GDDR5) one costs me about 90 euro and the 1024 MB (GDDR5) is about 110 euro, so I guess I'll take the 512 MB one if you say it's not expected to make a positive impact on Civ5.
Do we have a preference between e.g. ASUS, MSI and Sapphire?
Btw, I see some of these HD 5670 cards give a power recommendation of 400 watt. My computer has a built-in power supply of 375 watt. Is that expected to give problems when running at a moderate resolution of 1280 x 1024 or 1650 x 1080?
