SLI Compatability

[smasherton28]

So in my current system I have a PNY GTS 250, I'm planning on building a new system when I get home and I'm going to SLI. Currently on my wishlist on newegg I have an EVGA GTS 450, will these be compatiable? Or will I have to go with another 250?

For SLI they have to be the same Gpu type,but manufacturer is irrelevant

* Cards from two separate retail companies will work together in SLI mode, but they must be the same GPU model (e.g. G70, G73, G80, etc). The cards may have different BIOS revisions, different default clock speeds, or even different memory sizes. However, the fastest card - or the card with more memory - will run at the speed of the slower card or disable its additional memory.

* SLI doesn't always give a performance benefit — in some extreme cases, it can lower the framerate due to the particulars of an application's coding.[2] This is also true for ATI's CrossFire, as the problem is inherent in multi-GPU systems.

With crossfire it's a bit more flexible

Yes, with nVidia you need to match the model. Crossfire allows a little more flexibility and allows CF with some other select models.
