My 2-way SLI Geforce GTS 450 1 Gb perform well in games but a friend offer me a XFX 7850 1 GB for a very low price. How good is this VGA?
Depends on how low the price really is.....but I doubt anyone on this forum would recommend a 1GB card at this point.... I don't expect you'll see much, if any gain at all. The biggest downfall in each case is the 1GB of vram. If you're trying to play newer games, you'd be better off saving up some money and buying something with more vram.
You don't get 2gb of VRAM from running 1gb cards in SLI. The memory is mirrored, so you only get 1gb. I'd do as skyozis suggested and save for a little to get a decent 2gb + card if you're looking for an upgrade.
I know that. SLI don't add vram. Only say if i use 1 GTS 450 in Max Payne 3 in the option menu i got only 1 GB to change options, in SLI i got 2 and I able to actÃvate more configs. If I change for a 7850 1 Gb I lose this options. Recomend me a VGA please, around 350-550 dollars.
If you have 550$ USD and depending on were you shop one of the new R9 cards or A 7970 since they're clearing for 300$ here in Aus so prices should be close there. Or if you like Nvidia more and like getting charged more for same performance a GTX 770 will do nicely. Also GTX 450 SLI or 7850 1GB isn't a bad idea if your not using a monitor with a resolution of 1920x1080.But this again depends on how cheap it is.
