Hey Everybody! Since i have a SandyBridge System with 2 x 8x PCIE only and theyre already used, i looked for a solution for a dedicated physx card. Well i only had one free PCIE 1x 2.0 slot and thats it. So either i try to "open" (looking at my tiny saw) the slot for a longer pci-e card or i buy a new mobo! But then i found this: http://www.amazon.com/Zotac-GeForce...5UO4/ref=sr_1_4?ie=UTF8&qid=1329315800&sr=8-4 :banana: Ok so i thought before asking anbody and/or looking for some threads, i just order the card and try it myself, easy! 14days is enough for testing (i needed 30mins, from unpacking to see the physx arrow in gpu-z, i had a physx hybrid system before, so it was nothing). What can i say, it runs really really well! here are some numbers: Batman AC ALL Maxed 1080p: Min 15 Max 60 (vsync) Avg 35 Batman AA ALL Maxed 1080p: Min 34 Max 180 Avg 80 I get about 80% GT520 GPU Usage! Nice! Tested also Metro, Sacred 2 and runs really great i never thought a GT520 on PCIE1x 2.0 would make it but i was clearly wrong! So for everybody with the same problem, go ahead! Just try it yourself, i can def. say it works and everygame i tested been playable at least with absolute maximum physx + ingame settings. If you need more Information let me know, no Problem. Main reason for this threat is that Pcie-1x 2.0 does work sufficient for PhysX dedicated cards.:biggun: Have great day guru's!
