GTX or two GTS SLI

Hi,

About a month ago I was having problems with my PC restarting during gaming. To make my story short, after every trouble shoot I tried, I nailed it down to the power supply. That was after I went out and purchased two 450 GTS cards and hooked em up in SLI. The problem still occurred until I realized that my brothers 8800GTS card worked fine which meant not enough power to the video card. I disabled one card and everything works fine. Turns out the 295 GTX card I had required two sources of power and my PSU wasn't giving enough power.

I ordered a new PSU and I'm trying to figure out which would be better for me and powerful for gaming. Should I return the two 450 GTS cards or stick with my 295 GTX?

If you can get the money back for the 450 i would do that and try to save a bit more money for a newer and stronger one. There is no sense in paying a lot of money for a slight increase in performance i think. There is not so much difference in performance i believe ( 450 sli is faster but not that much ), only when you play a lot of dx11 games the 450 is better. ( 450 =dx11, 295 =dx10 )

Sounds good to me, waiting for my PSU to arrive so I can return my cards. You want me to get this? http://www.bestbuy.com/site/NVIDIA+-+GeForce+GTX+550+Ti...


No :non:  , thats about the same card as a 450 i think ( newer, so better, but still. ) I think $199 is a lot for that card, on newegg you pay around $140.( 119 after rebate ! ) For $199 you can have a much better 560 TI or for even less money ( $ 170 ) a normal 560 wich crushes the performance of the 550. ( i would go for the TI and maybe later on buy another one for SLI )
Also you can take a look at the Radeon HD 6870 ( $170 ) or better the 6950 ( it's more expensive though, about 240 )
By the way, are your processor and memory a bit up to date, otherwise a really expensive card might be to much ? ( you've got PCI-E 2 ? )

Intel i7 860 @ 2.80GHz
At the moment I have 4GB of memory but when my PSU arrives, my 16GB memory will arrive with it as well.

get a gtx 560ti they can easily be oc'ed to near 570 speeds; my asus dc2 model did. What psu did you order? I will try to give input as i can; I am procrastinating a ridiculous research paper for my summer class...

yeah the new drivers are nice I got my gtx560ti running solid at 1ghz core and low temps was just testing some just cause 2 and was getting some really nice frames maxed out at 1080p with everything considered its pretty much the performance of a gtx 570 imo, but if the OP can get the dual 460ssc off of the site that was linked that would be a sick combo for about the same price as a single ti

long story basically the original pny gtx 570 I got was a lemon, the refurb was a lemon and once I RMA'ed it I sold (gave) it to my cousin after being fed up with that model in general and having to make a new gpu purchase I went with an asus dc2 gtx 560ti. So far to be honest I can barley tell a difference, the 560ti ocs to beast levels. Of course the 570 when oc'ed would perform even better but for me the 560ti is all I need right now. Furthermore I am glad that I now have a reliable brand/model so basically that is my reasoning; although illogical this is what happened since I am so impatient with GPUs sometimes :)  in the end im happy with it until next gen gpu come out then I will likely upgrade to a higher end gtx6 or AMD7 series (likely the former) gpu.

Whos knows by that time it might be time for that new mobo/cpu and a second gtx 560ti for sli...

I've heard so much about the am3 sli hack but would like to hear from someone who currently runs it how it works...?

after being totally turned off by crossfire I am weary to try any sort of dual gpu config? how is the minimum fps of your 560s? stutter/flicker?

yeah the 990fx route seems like a good one... can you run 2 tis and my rig on a 650w psu though is the question... likely yes but there would probably be not much headroom im thinking

Yeah for the OP we will have to see what they think with the information given... if OP already has gts 450 sli then id stick with that and see how it runs with a new psu... although if money is no object DREAM BIG! go for a 560(ti) and a second for sli road and sell off your current hardware, that seems to be the most enticing option imo although gts 450 sli will suffice

do you OC to the max or just to a certain 'feel good' number.?


more of a feel good number I dont want to push my luck too much

for example my 955 is actually at 3.9 with stock volts although it can be pushed much farther, especially when increasing v past 1.4 ish

with the 560ti I currently have I am trying to go for a near max oc so far 1 GHZ core is 100% stable after hours of gaming... but in the case of the single gpu I need as much power as I can get. Also with a solid 3 year warranty on a brand new product I am willing to push my luck a little more I guess although I hate any RMA process

^there ya go a single 450 would be a nice physx card to pair with either gpu although I'd prefer paying a little more for the 560ti. The second 450 can be ebayed for a little cash towards the new purchase, just make a decent looking auction and it should take no problem.

yeah in order to make the upgrade worthwhile meaning the OP will actually gain performance in the process I'd just say go with the gtx 560ti its sort of in a different league then the 470 imo given its oc abilities although the differences between them may be miniscule, anyways so much for this banter I think the OP has plenty of input on this end :)

Here's my problem. I was in a great need for a Graphics card since my 295 uses a lot of power. Waiting for my PSU to arrive took a long time and I can't no longer return my video cards. I'm stuck with two 450 GS cards. I actually thought having two 450 GS cards would be better than the 295 I have.

From what I read, I can use a 450 card for phyX and my 295 as well? I'm confused but this is a good learning process. As for the 560 Ti, the ship has sailed. :(

^yes +1 my vote is for a 295 and a 450 for physx if the OP now has a good psu

I have a 1,000 Watt PSU. So you're saying with my duel monitors, I hook them up to the 295 and use one of the 450's as a physx? I've never tinkered with SLI until this month and never knew you could put two different cards and one as physx. Anyone care to guide me? :)  I love this, you learn something new every time you fall into trouble.

Never mind I think I got it. Just plug in the 450, go to NVIDIA Control Panel and set PhysX to the 450 instead of AUTO. :)

I want to thank everyone here for helping me. You guys have been very helpful and I've learned a thing or two about SLI and PhyX. As for the second video card, I'm not sure. I did a windows experience test and my 450's in SLI were 7.4. With the 250 card alone I get 7.7. Base score is 7.4. Primary disk is 7.9 thanks to SSD in raid0. I just ran a test with the 295 and the 450 set to physX and it comes out to 7.6. Not sure what's going on there. My processor and memory went up from 7.4 to 7.5. So I'm guessing the video card is taking the stress off the CPU. What do you guys think?

Yes the GTX 295 alone get's 7.7. I shouldn't put the 295 with the 450 in SLI correct cause that wouldn't work out? Let me see what happens when I clean sweep the drivers.

I did the clean sweep and re-installed the latest drivers from nvidia. The numbers still stay the same. I would believe if I used SLI with the 450's the numbers would be lower regardless of clean sweep. I think I'm better off with the GTX 295 but I'll give the 450 SLI a shot too with clean sweep.

How about this... 450 SLI and 295 physX? My board supports tri SLI so I have 3 slots.

That's a negative sir. GTS only supports 2 way SLI. Ummm...I think I'll just sell all 3 and get a GTX 560 Ti. Hell for $200, I'll SLI 3 GTX 560 Ti. Thanks for the help.

The GTX560Ti is only 2 way SLi capable.

I guess this concludes our trouble shooting. Thank you guys so much. In conclusion, I will get two 560 Ti cards in SLI and use the third slot for PhysX. I should be OK with the 1000 watt power supply I have. You guys are awesome, thank you.
