I want to maximize the hardware I have sitting around for my 2 boys' boxes. I need some help with a decision.
Son #1 is a gamer, so I plan on giving him my old ASUS P5Q3 since it runs DDR3 with a C2D E6600.
Son #2 is more productivity related, so he's getting an ASUS P5N-D running DDR2 and a C2Q Q8200.
1. Currently, #1 has a GTS250. Would he see a benefit if I put my old 5670's in Crossfire for gaming? The 5670 is equal to the 9800, but the 250 is better than both, but will the 5670's in Crossfire outdo a single 250?
2. Son #2 will then get the 250 or a 9800GT I have. I've read the hierarchy chart and know the 250 outperfoms, but are NVIDIA cards like Radeons where you don't need the EXACT cards to SLi? Could I put the 9800 and 250 in SLi?
a 9800 gt and gts 250 will not be compatible at all.in case of radeon cards a 5750 and 5770 can be put in for crossfire because they have same built in architecture with near same specifications.for choosing a card,get radeon hd 5670 in crossfire or get a single radeon hd 5770 which have dx 11 features unlike 9800 gt and gts 250 supporting only dx 10.
