Boas!!
A minha dúvida é a seguinte:
Num pc especialmente dedicado para jogos kual a vantagem de ter 2 Gráficas 8800GTX 768MB
ou apenas uma??
Será k vale MESMO a pena o investimento das duas?
Cumpz..
 
depende muito.. se jogares em resoluções enormes, vais ter bastante impacto
se jogares em resoluções inferiores tens o extra de teres uma a aplicar os filtros tipo AA e AF e outra a processar os graficos propriamente ditos..

SLI offers two rendering and one anti-aliasing method for splitting the work between the video cards:
  • Split Frame Rendering (SFR), the first rendering method. This analyzes the rendered image in order to split the workload 50/50 between the two GPUs. To do this, the frame is split horizontally in varying ratios depending on geometry. For example, in a scene where the top half of the frame is mostly empty sky, the dividing line will lower (so that both cards have an equal share), balancing geometry workload between the two GPUs. This method does not scale geometry work as well as AFR, however.
  • Alternate Frame Rendering (AFR), the second rendering method. Here, each GPU renders entire frames in sequence - one GPU processes even frames, and the second processes odd frames, one after the other. When the secondary card finishes work on a frame (or part of a frame) the results are sent via the SLI bridge to the master GPU, which then outputs the completed frames. Ideally, this would result in the rendering time being cut in half, and thus performance from the video cards would double. In their advertising, NVIDIA claims up to 1.9 x the performance of one card, with the dual-card setup. (There is another mode, AFR2, which can be manually chosen, but NVIDIA has not documented the difference between it and normal AFR.)
  • SLI Antialiasing. This is a standalone rendering mode that offers up to double the antialiasing performance by splitting the antialiasing workload between the two graphics cards, offering superior image quality. One GPU performs an antialiasing pattern which is slightly offset to the usual pattern (for example, slightly up and to the right), and the second GPU uses a pattern offset by an equal amount in the opposite direction (down and to the left). Compositing both the results gives higher image quality than is normally possible. This mode is not intended for higher frame rates, and can actually lower performance, but is instead intended for games which are not GPU-bound, offering a clearer image in place of better performance. When enabled, SLI Antialiasing offers advanced antialiasing options: SLI 8X, SLI 16X, and SLI 32x (8800-series only). A Quad SLI system is capable of SLI 32X antialiasing.

googla, antes de dizer que SLI nestas placas não vale a pena..
 
A que resolução vais jogar mesmo?

É porque é só naquela.. 2 8800GTX ultrapassa os 1000€! E lá para novembro acho que já vai haver a 9xxx GTX.. assim vão desvalorizar imenso.

E se for para jogar a 1024x768.. então não vai valer a pena na minha opinião :)

É assim,ainda estou indeciso se compro um tft 19" widescreen ou de 20" widescreen!!
Fogo isto é mesmo indeciso,nem sei o k fazer!!!!kero fazer um bom investimento pra futuro e sendo assim já nem sei se troco de motherboard pra fazer SLI!!!!
Ñ sei k faça!!;«

um bom investimento para o futuro.. simples... compras uma 8800GTX e o resto do dinheiro da "suposta" outra 8800gtx mete de lado, no natal ou coisa assim parecida.. sai novas graficas.. e aplicas o dinheiro dessa "suposta" 8800gtx nessa gráfica :)


Penso que e' a melhor opção, mas tu e' que sabes rapaz...
