*The reference GTS 250 lacks TV-Out.

The only change to the reference design, apart from the new PCB and heatsink, is the omission of a TV-Out connector. Support for triple-SLI remains.


The 9800GTX+…

Note that, while 1GB versions of the GTS 250 will at release already be
using the new reference design or manufacturers’ own custom designs, a 512MB card might be a 9800GTX+ with a BIOS flash, at least until old stocks are cleared out.

So if you must
have a shorter card to fit into your small form factor PC or something like
that, go for the 1GB version of the GTS 250 or wait some time for the old design to be cleared out of existing stocks.


…and the GTS 250.

The cards from Galaxy and Twintech that we have here today
are not reference cards though. No doubt as part of Nvidia’s grand
scheme to create the illusion that the GTS 250 is a new card entirely,
many partners are releasing self-designed GTS 250s utilizing custom
PCBs and heatsinks.

Both cards are 1GB versions of the GTS 250, and utilise custom heatsinks and PCB designs.

*Up to two of the outputs can be used at any one time.

Somewhat strangely, Galaxy’s GTS 250 lacks a
factory overclock. Twintech isn’t that much better off either – its
factory overclock is downright meagre.

While
the triple outputs on Twintech’s card may look tantalising, the truth
is that the two-display limitation of the G92 still applies. That
additional HDMI port just saves you the trouble of using an adapter,
nothing more. On the outputs front Galaxy has simply replaced one of the DVI ports with a HDMI output, and also retained the TV Out port.

So without further ado, let’s start off by looking at Galaxy’s GTS 250.
