|  What is meant by Nvidia SLI and ATI CrossFire ? Nvidia SLI and ATI CrossFire is basically a solution for using multiple graphics card on a single PC with a single motherboard . Nvidia Scalable Link Interface Quote:
ATI CrossFire It is a similar technology used to connect multiple ATI Graphic cards and produce a single output .Rivaling the SLI Technology . For such a set up using SLI you need -->An Sli enabled Motherboard (Preferably from Nvidia) -->2 Similar Nvidia Graphic cards -->SLI bridges The SLI Bridge essentially serves as a connection between the 2 cards . The 2 Cards are in a master slave relationship . That is if a 3d scene is given to the 2 cards to render . One card (Master) renders the upper scene . while the slave card renders the lower scene and passes this to the master card through the SLI Bridge .The master card then connects the 2 halfs and renders it finally to the monitor . NOTE : Note : It is Better to buy a new single card than sli 2 cards imo..... Contrary to popular belief 2 sli ed cards give you a performance boost of any where from 60% to 90% depending on your card** not a 100% boost as it should be .So Even though you pay twice the price for the 2 cards you dont get twice the performance! **According to Nvidia's statement Most Recent Technology NVIDIA 's Quad SLI As the name suggests 4 Nvidia Graphic cards can be connected together to produce a single output ATI's CrossFire X A Similar technology allowing 4 ATI Graphic cards to be connected together to produce single output .

Rep Power: 2  |  Well you will also need a good power supply with atleast 50 amps if you are using mid range cards. Not to mention air to circulate around. If you see want to see a scaling difference on crossfire/sli upi definatly got to have screen of a great resolution than 1650x 1050. |

| Yes SLI does produce a lot of heat and needs an extra fan or some kind of non-passive cooling solution |

| Quad sli...... can u giv the link to a board that was 4 pcie slots (for NV)... as far as i have seen, they have tri sli till now and the only ones that can do a QUAD sli are their dual gpu solutions (eg 9800GX2 X 2 = quad sli) |

Rep Power: 2 | Well the i7 processors have a TDP of 130w- literally double the ones he was now. Though its pretty sad that is defeats the high end core 2 extreme by a small margin on stock, it shows that ones needs to invest a equally good power supply. Sliing cards like 8600gt is plain silly. You rather buy 1 single card. Besides the common screens that we get in cheap rates are TN panels. I have seen my friend's pc running a palit 4870 1GB dual sonic being run on an s-ips panel based dell 3008wfp and the colour was FANTASTIC. One has to have equally worthy cards to sli/crossfire, screen and resolution, power supply and good enough case to keep it working properly without any hassles. |
