Your mic and speakers are more than decent. Check in Prefernces  if you are running Sonar in ASIO mode. If you still have glitches raise latency. If glitches disappear but latency is to high to accept thats when you need to look into computer specs (post it here) and perhaps interface.

Thank you so much  for your responses.
I think getting everything even is good advice gtzwitz but how do you know what that is?
As regards budget.... well, i guess £2000 ish, maybe a bit more if i have to change pc as well.
I don't need to record instruments or multiple voices and my studio is in a converted garage (which also doubles as my workspace / salon) only treatment it has had is cavity wall insulation, nothing special. but i have great neighbours (detached) who don't appear to hear me too much. As regards PC spec, I will have a look at how i find that out and report back (its about 6 years old now) thank you all.

For computer specs, you can go to "computer" in your start menu and then click on system properties.  That should show you your processor type and memory.  My guess based on the age is that you might want to upgrade it.


Here is a pretty basic list of stuff that you might need/want in a project studio (in sort of a priority order):
Audio Interface preferably with ASIO drivers (2-4 inputs based on what I think you are going to do with it)
Microphone (you have one that will work)
Headphones (if you are recording with the mic, you will want phones, you can mix with them as well)
USB Midi keyboard controller (if you are planning on doing an Midi stuff)
Audio monitors (you have some which will work)
Various stands/cables
 
Also, regarding the audio interface - if you decide to upgrade your computer, you will need to make sure that it has USB2 ports or get an interface that is compatible with USB3 (assuming you get a USB interface.)
 
Also Tweakheadz has a great guide on project/home studio recording.  It can be found here.

Another thing that's important... what do you want to do?  what synths/vsts do you have.  With a 2000$ budget spread over all the essentials I think RME is really OVERKILL... there are a lot of good stable interfaces from focusrite, NI, presonus, among others...for a couple hundred bucks.
 
If I were to "have" or "buy" one instrument that covers virtually ALL the bases and for which there is lots of youtube instructions (skippy at plug in guru) it would be Omnisphere2.  I have a zillion things... that is the one i would keep way above any other piece of gear. It can do pretty much anything you can imagine.

For me personally, a good interface is paramount. Everything sounds better and works better, even with older software or PCs. I would really hate to recommend a collection of "almost" good gear to someone who comes in here complaining of issues. I would rather sink 500/1000 in a serious interface than make do with another 200 bucks half-solution that got the OP where he is now. As always, your mileage may vary. 

Here are my computer specs I'm not sure which bits are relevant so I am just typing all of it
model: ixtremeM3720 rating 3.3
processor: intel (R) Core (TM)2 Quad Pro Q8300  @2.50 GHz 2.50GHz
RAM 4.00GB (3.75 usable)
64 bit  05
 
I now use only the soft synths that come with Sonar, I used to have a Roland JV1010 but I got rid of it because I couldn't really tell much difference in sound quality and it freed up some space on my desk.
In terms of what I want to achieve. I want to keep to have the ability to write and compose with as few gadgets as possible and then record vocal on top. I would also like to put some of my songs onto the internet and see what other people think of them.
 
I am in the UK so I need stuff that's available here
 
Is it worth me getting a midi keyboard (as I can't play) ? I usually just input via the piano roll.
 
Thanks everyone for your thoughts and advice.
 

Hi Molly.
 
To be brutally frank, I think your computer is seriously underpowered and you should consider spending a chunk of money on getting a new one, along with a suitable interface.
 
Have a look on the Carillon website:
 
http://www.carillonac1.com/tower-core-1.html
 
They sell a variety of computers at a competitive range of prices and they will also configure an audio interface for you as well as any software you want installed.
 
There are other sellers in the UK market so shop around.
 
DEFINITELY get yourself a Midi keyboard, your workflow will speed up enormously. Again, you need not spend a fortune on one and again, Carillon will supply & configure into your system.
 
You'll get a sizeable chunk of change from £2,000 if you do your research carefully

Left Click Once on Computer to the right of START menu to select it, The right click and select Properties.  That will show you CPU & RAM as well as Windows Version (Pro, home, etc.).
 
If you need help with PC set up, there are Pros here that can build them for you (
Jim Roseberry for one).  I hear his systems are stable and quiet.  He will also consult with you and give you information if it does not make sense to ship the thing across the pond.  I definitely recommend this path since he has already figured out how to solve all the recoding issues (clicks and pops, slow machine etc.).
 
 

Taking a look at Jonesey's site, I found this for under 2000£

Just a thought..
All the best.

Ken, is that link meant to take me to a shopping cart with stuff in?
