Hi Guys.

I'm hoping to upgrade my Gaming Rig to a more powerful machine as I have new funds that I didn't when I first built it. Here is my rig:


YOUR BASKET
1 x Gainward GeForce GTX 570 1280MB GDDR5 PCI-Express Graphics Card £254.99
1 x Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor - Retail £159.98
1 x MSI P67A-GD53 Intel P67 (Socket 1155) DDR3 Motherboard ** B3 REVISION ** £107.99
1 x Microsoft Windows 7 Bundle - Home Premium 64 Bit £68.40
1 x Western Digital Caviar Blue 500GB SATA 6Gb/s 16MB Cache - OEM (WD5000AAKX) £32.99
1 x Antec TruePower New Modular 650W '80 Plus Bronze' Power Supply £65.99
1 x Corsair XMS3 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (CMX8GX3M2A1600C9) £57.59
1 x LG CH10LS20 10x BluRay-ROM / 16x DVD±RW Drive - Black (Retail) £52.99
1 x Cooler Master Elite 430 Windowed Case - Black £37.99
Total : £853.91 (includes shipping : £12.50).



Now I was wondering:

- Can I buy any card and SLI it with the current card (since my card has a DP port and I have to have one for output) or do I have to use 2 of the same card?

- The other question is, will my PSU be powerful enough for this? It says SLI ready on the box but I want to be sure.

- I was thinking about SLi-ing this card in the future (again it must have a DP) but it's not important as I suspect 2x my current card will max out even BF3.

Any help will be greatly appreciated.

Thanks,
Mike
 
You could get away with your current PSU with SLI 570, It would better for 750 to 850w.

As you already have a 570 I would buy another one, rather than upgrading to the 580 and SLI tha I the future.
 
SLI would still work if the cards had different amounts of memory, but the card with more memory would be a waste, since VRAM in SLI is not added together. The VRAM is mirrored, so the card with the lower amount of VRAM is the amount you would actually have to play with.

Same general principle works with different memory DIMMs, if you mix and match, they will all run at the speed of the slowest DIMM.
 
So to get maximum efficiency I should have two exactly the same cards. Do you guys think SLI of my current card will be powerful enough for say something like BF3 on max?
 
doenst matter what brand gfx card u get just much have the same ammount of ram. doesnt matter is the new card is overclocked, only that it will down clock itself to match the old card, sli 570'ss will be great for bf3
