Hi all. Im looking to upgrade my GPU with the aim of improving framerates for MS FlightsimX and Quake4 primarily. Currently im running a 6600GT 128mb card. As far as i can see ive got 3 options from what i can afford:
1. 8600GT (512mb DDR3 or 1GB DDR2)
2. 9500GT (256mb DDR3 or 512GB DDR2)
The 3rd option prob is not gonna be anywhere near as fast-
Get another 6600GT 128mb and set it up as SLi (My Mobo is Abit Fatal1ty FP-IN9). The only advantage of this is i can get the card for £10.
Also just a quick dummies question, i will be fine running DDR3 ram on my GPU and DDR2 ram on my Mobo?
Just found an XFX 8600GT Fatal1ty 256DDR3 running @ 620Mhz which it claims is the fastest 8600GT. That better than higher RAM?
Not sure about UK prices, but at the 1.8x exchange rate, that would be a horrible deal by US prices. You can get a far better performing 9600gso/8800gs for less than that. Search around for better deals.
Seriously the HD4670 is the card for you. It's way faster than those two choices (8600GT and 9500GT) and it doesn't require an auxiliary power connector so you won't have to worry about upgrading your power supply.
To be honest it's not really worth doing SLI, by the time you end up wanting to upgrade there might be newer/more affordable cards at the same price range that are a lot faster. If you want to stick with nvidia that's your choice, but at your limited budget that's a luxury I wouldn't take.
