Vista - Graphics Card/Motherboard Question

Hey All, i currently own a Dell Vostro 410 desktop and was wondering if my motherboard supports SLI?
Board: Dell Inc. 0J584C A00
If it is not SLI compatible, is there anyway of making it SLI without changing the motherboard.
If the answer is no to the above... then do you suggest i overclock my 512 mb Nvidia 8800GT or just buy a new graphics card with double the memory... the real problem is that i want to enjoy playing high intensive games at 1680x1050 but at the same time not get graphics lag.
Lastly, any suggestions of good graphics card with the budget of £1-£90

I don't think it is SLI compatible, and the only way to change that is to upgrade the motherboard.

If you can stretch to an extra £10 or so, (£15 including postage on scan.co.uk), then I'd recommend this card GS-250X-YDFC - 512MB XFX GTS 250, PCI-E 2.0 (x16), Mem 256Bit 2200 MHz, GDDR3, GPU 738 MHz, HDTV/DVI, Retail - Scan.co.uk. Or you could get something like an ATI Radeon 4850 as well Computer Hardware - All - GPU - ATI - Scan.co.uk, but again you'd need to stretch your budget a bit more.

The only card you could upgrade to in that price range is a 9800GT or something, but that won't really give you a noticable difference over your 8800GT.

Thanks for the quick reply and the very helpful feedback. In you opinion which card do you suggest i get. One other question instead of buying a new card, do you recommeand that i overclock my Graphics card?

Overclocking graphics cards has, at best, minimal effects. It is mostly used for benchmarking and E-penis.

A used to have an 8800GT and it was great, it overclocked well, but the real-life performance increases were very, very minimal.
