Hey guys,

I've just started getting into mining, and just had a few questions regarding these cards.

I already know that for mining, the EVGA cards aren't the way to go, but I'm starting out with an already built system, and plan on using this for a bit while I debate whether or not I'm going to actually invest in a dedicated rig.

I'm currently using the GUIMiner on BTCGuild server, and I'm getting around 115Mhash/s per GPU. (I have 2x running)

I was wondering if anyone could give me some tips as far as the flags go, as I've looked around and haven't seen much in the way of the NVIDIA GPU Chipset.

I'm also somewhat curious as to what kind of settings I can set to be able to use my system while it mines, and not worry about lag, as I experience quite a bit of lag with it running, and have also experienced system failures on occasion. Also wondering if there's anything I can do to possibly increase my average hash rate with my current setup.

Any tips you can provide would be greatly appreciated.

Anyone able to help? Also, if I don't go for a dedicated rig, but rather decide to just change out my video cards (I've already done the research, and my Mobo will support the ATI cards, so that's not a problem) - What would be a good equivilent to the 480's, or possibly something better in regards to gaming, as I was already planning on upgrading, this may just be the step that forces my hand.

I have a GTX 580 that I use primarily for games, but when I'm not playing games, it's mining at a rate of about 127 Mhash/sec. I recently purchased a used HD 5870 for the purpose of mining, and I put it in the same system with the GTX 580.

Currently, the HD 5870s and HD 5850s give you the best price/performance ratio for mining bitcoin. I don't have any first-hand experience with the HD 69xx series, but if you're looking for a video card upgrade for gaming, and also intend on using it for mining, it's probably worth a look, though I don't think mining performance is much better with the HD 69xx.

As far as system failures go, did you check to see if your rig was overheating? Perhaps turning down the aggression level in the miner would reduce the lag, but I'm not mining when I play games.

Well, I did a little reading earlier while I was at work, and discovered that the memory clock was virtually unneeded while mining, so I underclocked that as low as it will go. That dropped my average temp by around 10C from 90 to 80, and I'm still able to use my system normally (this is, not gaming. If I game, I pause the miners)

Currently I have the Core clock overclocked to 850, and the mem clock underclocked to 1400, and I'm getting ~120mhash/s per card.

Anything else I can do to increase stability/hash rate, or is this about the max I'll get with my current setup.

Also, i've been pricing cards on newegg, and I'm highly considering making the upgrade/switch within the next few days, to possibly the next week, so any more suggestions on cards would be great. If any other info is needed about my system, just let me know and I'll provide it asap.

nVidia cards=Raise all values
ATi cards=Drop mem

Now then, The best bang for buck cards are ACTUALLY not the 58xx's
It is the 5830's!!
Im running a $114 Shappire 5830 @260mhashes. Beat that!
the $140XFX ones hit 290mhashes wich is Much better.

I have a Dual 6990 rig and i regret it, Each core pulls 334mhashes and each card has two gpus, So 1300mhash/sec, Cards were 750ea
AND THE MOTHER FUCKERS ARE HOT, 100°'s when fan speeds are at 100%, and the case has around 8fans in it aswell. Altough, if i take off the sidepanel, And stick a Massive desktop fan right next to it (the really big ones 120V 50W) then the fan speeds drop to 80% and the temps drop to a beautiful 85°.

Do not buy 6990's unless you are accounting for Moores Law,
If your just mining, Buy a fuckload of 5830's, They run cold, Overclock well, And suck at gaming, PERFECT MINING CARD

My 6990 does 420mhash/core so you might want to check your settings. But i agree 5830s are more bang for the buck

As for
"nVidia cards=Raise all values
ATi cards=Drop mem"

I actually found that incorrect. As I stated earlier, my hashrate hasn't changed., but yet my gpu's are running 10C cooler with the underclocked memory.

As far as the rest goes, I'm not sure whether to build a dedicated rig or to just turn my gaming rig into a part time miner for now, then build a rig later. That's the biggest battle I'm currently fighting with myself. I'm seriously considering just upgrading/converting my current pc to a part time  miner, then later on down the road, build a second PC as a full time miner.

One other thing I didn't mention, is electricity costs are irrelevant to me. I live in the barracks, so that's all paid for.

My ONLY internal conflict right now is this:

Upgrade Current PC for part time mining while I'm sleeping/not gaming, then later on down the line build a dedicated rig

OR

Just go straight for the dedicated rig.

Mind showing me where you found the 5830's for that price, and actually in stock? I'm looking around online and finding absolutely nothing in stock for a price of less than like $200....
